Hello World!

I'm a newbie programmer and I want someone to please help me with the differences btw the following:

1.) a = a + 1

2.) a =+ 1

3.) a += 1


God bless you guys.

For languages that supports it. A += 1 is a shorthand for A = A + 1. It used to be an optimisation technique, but right now it is part of a style of programming, it offers no significant gain in speed of the programme.
A =+ 1 is a syntax error.

Thanks

Please what is the difference btw a++ and ++a

eg if a=3 a++ means 3+1 ... ++a means 1+3 ... hope this help u out a little.

Please I need a pro to check this code for m. Its a program should accept input for user and count the number of vowels and consonants.

The Code:

v_count = 0
c_count = 0
alphabets = []
vowels = ['a', 'e', 'i', 'o', 'u']
consonants []

for i in vowels:
....vowels.append(chr(ord(i)-32))
....#update the vowels list with caps
for i in range(65, 91):
....alphabet.append(chr(i))
....alphabet.append(chr(i+32))
....#update the alphabets list
for i in alphabets:
....if i not in vowels:
........consonants.append(i)
........#update the consonants list

text = input("Enter text:\t"

for letter in text:
....if letter in vowels:
........v_count += 1
....elif letter in consonants:
........c_count += 1
....else:
........continue

print("vowels: " + str(v_count))
print("consonants: " + str(c_count))
