In Python 3 we cannot increment a variable directly with "++" before or after this variable.
We have to add + 1 on the variable to increment it.
That’s a bit annoying but life is life.
In this tutorial we are going to see examples of the Python 3 statements.
While statement
We use the while statement to iterate through a number. An int for example.
Code
i = 0
end = 10
while i < end:
print(i)
i = i + 1
Result
0
1
2
3
4
5
6
7
8
9
For statement
We use the for statement to iterate through something that have data such a string (has characters), an or a list (have items) for example.
Code with a string
i = 0
myString = "Hello World!"
for i in myString:
print(i)
Result with a string
H
e
l
l
o
W
o
r
l
d
!
Code with a list
i = 0
myList = ["Hello", 8, "World", 99]
for i in myList:
print(i)
Result with a list
Hello
8
World
99
Easy but useful.
