I'm sorry for derailing the thread, guys. Pls, can someone explain what mutable and immutable data types are?? I understand that mutable can be changed and immutable cannot be. But, how do you write the codes?? The codes look smh confusing. For example:
list_values = [1, 2, 3]
set_values = (1, 2, 3)
print(id(list_values))
print(id(set_values))
print()

list_values += [4, 5, 6]
set_values += (4, 5, 6)
print(id(list_values))
print(id(set_values))

Output:
515314983168
515315121920

515314983168
515315333056

I don't understand how the code produced that. Pls, can someone explain

def min_max():
    list_number = []
    while True:
        num = input("Please Enter a number: " )
        if num == "done":
            break
        else:
            try:
                list_number.append(int(num))
            except ValueError:
                print("Invalid input" )
    print(f"Maximum is {max(list_number)}" )
    print(f"Minimum is {min(list_number)}" )

Hello guys,

could you help look at the code; this is what i'm trying to achieve but not quite getting the output desired

Write a program that repeatedly prompts a user for integer numbers until the user enters 'done'. Once 'done' is entered, print out the largest and smallest of the numbers. If the user enters anything other than a valid number catch it with a try/except and put out an appropriate message and ignore the number. Enter 7, 2, bob, 10, and 4 and match the output below.
Desired Output
Invalid input
Maximum is 10
Minimum is 2


num = input("Enter a number: "
largest = num
smallest = num
while True:
num = input("Enter a number: "

if num == "done":
break

try:
int(num)
except:
print("Invalid input"
continue

if largest < num:
largest = num
elif smallest > num:
smallest = num

#print(num)

print(f"Maximum is {largest}"
print(f"Minimum is {smallest}"

thanks @ zizytd

i see what you did using a list. I am just starting on python and this was an exercise on loops and iteration, haven't really explored lists. This exercise took a long time for me to solve but learnt a lot on what not to do. eventually got it right:


while True:
num = input("Enter a number: "
try:
int(num)
except:
print("Invalid input"
continue
num = int(num)
if type(num) == int:
break

largest = num
smallest = num

while True:
num = input("Enter a number: "
if num == 'done':
break
try:
int(num)
except:
print("Invalid input"
continue
num = int(num)
if num > largest:
largest = num
elif num < smallest:
smallest = num
print(f"Maximum is {largest}"
print(f"Minimum is {smallest}"

@zizytd,

also in your code, after the except you put valueerror, is that necessary?

zizytd:
try and except is to catch possible error messages , for this why I used ValueError because if you put int("bob" you will get a ValueError error. If you don't put the type of error it catches all kinds of errors(eg ValueError,TypeError,OsError etc). So it will still work but the only problem is when you want to catch a particular type of error message.

Happy New year to you all.. I hope you enjoyed the festivities..

As one of my plan for the new year, I will be teaching python programming for the next 30 days. After these 30 days, you will be opened for a lot of opportunities in the programming world.

The reason I've chosen python is because it can be used for almost everything ranging from web development to game development to desktop app development to Data Science and Machine Learning.

I have carefully selected the topics to teach for the next 30 days, including projects so as to make you understand the concept of programming and python.

Feel free to post questions on this thread or in the comment section of the YouTube video.

DAY 1
INTRODUCTION


https://www.youtube.com/watch?v=V8zccWt7NU4

The python Programming Language is one of the most sought for languages today. Reason is because it can be used for the following:
1. Web Development
2. Game development
3. Desktop Application
4. Android Development
5. Data Science/ Deep Learning/ Machine Learning

Understand how to prepare yourself for the python journey or easy transition if you are migrating from another language to python

I’m looking for a programmer to help me do something 30k every month for doing some assignment cause this programming of a thing is not my calling

abatechz:
If you find mastering the code difficult, try the GUI program Tkinter It makes work easier when building desktop apps, I'm still trying to understand how it can be used for Web apps.
