HOW TO USE hasattr,getattr AND setattr
>>hasattr is to check if a particular object/class has a
particular attribute.
syntax hasattr(obj,attribute_name), it return True or false

>>getattr is use to get the value of an object(function,variable,class and other object),
if available else it return AttributeError
syntax is getattr(obj,attribute_name)

>>setattr is used to set the attribute of an object
syntax is setattr(obj,attribute_name,value)

Example:
class Person:
    p=locals()
    def __init__(self,fname,lname,age):
        self.fname=fname
        self.lname=lname
        self.age=age

    def fullname(self):
        return '{0} {1}'.format(self.fname,self.lname)

Bob=Person('bob','alex',20)
print(hasattr(Bob,'fname')) #return True
print(hasattr(Bob,'lname')) #return True
print(hasattr(Bob,'fullname')) #return True
print(hasattr(Bob,'age')) #return True
print(hasattr(Bob,'DOB')) #return False

print(getattr(Bob,'lname')) #same as Bob.lname return alex
print(getattr(Bob,'fullname')) #return function object like <bound object....at 0xefbad> same as Bob.fullname
print(getattr(Person,'fullname')) #same as Person.fullname

setattr(Bob,'age',40) #same as bob.age=40
print(Bob.age) #return 40

I will personally donate NGN240, 000 a scholarship fund to 5 individual for 12 months, to learn software design, mobile application design, software architecture, UI/UX, OS design and web design @ diib Academy.

Also will pledge NGN 100 000 investment fund to 5 Startup, SMEs, for 6 months. To support small businesses to invest the funds in SEO and ICT through diib Nigeria.

The white people do this to support Startup, SMEs and small businesses to grow faster. Many Tech company's CEO in US donate funds to assist business owners. Some companies make their quality services free because of the pandemic, to protect their small businesses.

I will do the same in my country in my own capacity. I encourage others to do the same.

I interested in software development (Blockchain Field) and currently building a Blockchain software using python just to learn.... Help a desperate and passionate python programmer

Video look boring to me,i use pdf for all my learning

DO YOU KNOW THAT else KEYWORD WORKS WITH while AND
for LOOP?

the purpose of else statement in for and while loop
is to get executed when loop ended without break
statement

example1
this for loop statement end with the help of break so
else statment wont be excecuted

for i in range(1,5):
    print(i)
    if i == 4: break
else:
    print('hi')

output: 
1
2
3
4

example2
this for loop statement end without the help of
break,so else statement get executed

for i in range(1,5):
    print(i)
else:
    print('hi')

output: 
1
2
3
4
hi

example3
using while loop 

start=1
while True:
     print(start)
     start += 1
     if start == 5: break
else:
   print('hi') 
   

output:
1
2
3
4

start=1
while start < 5:
     print(start)
     start += 1
else:
   print('hi') 

output:
1
2
3
4
hi

ACCESS CLASS ATTRIBUTE IN FEW LINES OF CODE USING VARS()

Let assume you have class profile and its attributes,
you can access them in two lines of code compare compare
to what we know before

example:

'''

class Profile:
    def __init__(self,name,age,sex,nationality):
        self.name=name
        self.age=age
        self.sex=sex
        self.nationality= nationality
        
 
obj=Profile('sam',20,'M','Nigeria')
#it is boring to access each attribute using attribute name like this
print(obj.name)
print(obj.age)
print(obj.sex)
print(obj.nationality,'\n')

'''
output:
sam
20
M
Nigeria

problem with that approch is that,it is boring
to update and write for large attribute,the lines of
code to use is equal to number of attributes 
'''

# A fast approach is using vars() 

for key,value in vars(obj).items():
    print(value)
    
'''
output:
sam
20
M
Nigeria

wow we achieve same result in just two lines of code
regardeless of the number of attributes

Note: side effect of this approch is that,it is unordered
'''

TYPICAL MICRO BUG YOU MUST AVOID IN PYTHON

There is often hidden bug that most begginers
do encounter when using conditional statement

example

sex='F'
if sex == 'M' or 'm':
   print('Male')
else: 
   print('Female')

#ouput : Male

"""
hmm...but why is the output Male? This is how python evaluate the
if statement above.

it evaluate from left to right starting with

sex == 'M' which return False,then evaluate the
result with next condition,

False or 'm' which is True,

if you are worried how we evaluate bool and str, here
is how it works bool('m') return True,so in real sense
we are evaluating False or True which make us arrive
at True,now sex == 'M' or 'm' result to True which
make code under if triggered. the way python see above
code is this

sex = 'F'
if True:
   print('Male')
else:
   print('Female')

to correct the bug, just rewrite the code this way"""

sex='F'

if sex == 'M' or sex == 'm':
   print('Male')
else: 
   print('Female')

#output: Female

Brukx:

Show us how

[Code]
[/code]

Change C to c

Example 

class hello:
    pass

Area where i think should improve on is how to use @property decorator to change the behavior of getter methods where necessary, remove setter method where not needed and the class will be perfect. Just my few cents

Please do anyone know about Blockchain development job in Nigeria? should share his/her experience, the possible market size and future outlook in few years

What is sentinel?

Sentinel in programming is a value that help to stop the execution of a sequence.

E.g

age=1

while age > 0:
    age=input('enter your age:')
    print('your age is ',age)

dauddy97:

Let me add to this.
I see no way, learning Programming will affect your studies.

I do have lecture from morning still evening most time and i must revise all note taken that day,you see that no time Left to pick programing for 1hour.

what works for you might not work for me

dauddy97:

Learning Programming makes you smarter and be able to think logically. If you find Programming easy, bro your studies will be piece of cake.

Am with you on this bro...programming will change your thinking

saheedniyi22:

I'm a Python programmer with machine learning knowledge,
I've seen your thread on Python best practices but it looks tough I don't seem to get some stuffs there, kindly recommend some texts or courses I can take that will help me improve( especially on Data Structure and OOP).

Thanks

On Data structure

Data Structures and Algorithms in Python by Michael T. Goodrich , Irvine Roberto Tamassia , Michael H. Goldwasser

Data structure and algorithms in python By Benjamin Baka


For OOP use realpython.com and learn class diagram (search on google for this)

TMwise1942:
Please can someone learn programing while going to school, and won't be distract answer is needing please � thanks in advance

I started learning python before i got admitted and still learning in the education system,currently in 300L geology and 4.55 CGPA

What help me is that i focus on programming in holiday and go off when i resume back in school

Currently i have acquired various skills in computer science

1.Data structure
2.OOP
3.backend development using django

I am an intermediate python programmer

Just schedule your time and dont be carried away by programming in school

How To Use Index Method In List

To find the first position of a particular element in a list,index
method get you covered;

the syntax is
list.index(element [,start[,end]]) (start and end are optional)
'''

fruits = ['banana','orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana']
#let get first position of banana
print(fruits.index('banana')) #output: 0

#To specify where searching to begin,add optional arguement start position

print(fruits.index('banana',5)) #output: 7

# The searching start from kiwi i.e  fruits[5:]

#you can also specify where searching should stop

print(fruits.index('banana',1,5)) #output:4

#here searching begin at position 1 (orange) and end at position 5(kiwi)

Lateztblog:
Whenever you post u experience you got low views like 100+
This is what to do!!!

Whenever you want to post, don’t post MIGHT LIKE. Post what THEY LIKE.

For example I post

1:BUHARI is going to China and also post
2:TRUMP is going to China
Which one do u think people will view most

Of course buhari is going to China bcuz we live in Nigeria we don’t have much business to do with trump... they MIGHT LIKE to view TRUMP IS GOING TO CHINA. But They LIKE to view BUHARI GOING TO CHINA

IS THIS FEED HELPFUL?: yes or no

Don’t forget to check www.lateztblog.

Lolz...post about snake on Nairaland ,you will see how people will rush your post

REMINDER: bool of empty string is False and bool of
any string or character is True
'''

x='' 
y='hello' 
print('bool of x is ',bool(x)) #output: False
print('bool of y is ',bool(y)) #output: True

Dwise19990:

Now I see where our mathematics is applied

If hou learn algorithm analysis, you will appreciate math more because it bring math closer to real world

Dwise19990:

Now I see where our mathematics is applied

Yes....in Nigeria school, they just hardcode math into our brain without no full application

iCode2:
Nice! You're set for it.

Not fully set,but moving closer

Pls add me o oo 07060435624
