How do you increment a variable in a for loop in Python?

Can we use increment operator in while loop?

The loop is starting with ‘i=0’ and then entering the loop with “i++” and becoming ‘i=1’ then the condition is checked over “i” so in the last loop when ‘i=3’ the loop is executed and then checked for “i<3”. So the loop is repeated thrice. The reason is u are using post increment.
