What is the difference between Post and Pre increment?

Question

Sir I wrote this

i = 1

i =+ 5

print(i)

Output: 5

Doubt: sir it should show 6 ryt?
Also when I tried += then it showed me 6. So, which one is correct sir?

I AM CONFUSED THAT HOW THESE TWO ARE DIFFERENT.... :(
Also the names I got from google (that post and pre increment)
So clarify please sir :(

Answer 1

Hi! In your example this is no post or pre increment. See this:
++x - pre,
x++ - post

Answer 2

When we increase the value of a variable before assigning it to another variable then it is known as Pre-Increment. When the value of a variable is incremented after assigning it to a variable, it is known as Post-Increment.
