Increment and Decrement Operators in Python
If you’re familiar with Python, you would have known Increment and Decrement operators ( both pre and post) are not allowed in it.
Python is designed to be consistent and readable. One common error by a novice programmer in languages with ++ and — operators are mixing up the differences (both in precedence and in return value) between pre and post-increment/decrement operators. Simple increment and decrement operators aren’t needed as much as in other languages.
You don’t write things like :
for (int i = 0; i < 5; ++i)
For normal usage, instead of i++, if you are increasing the count, you can use
i+=1 or i=i+1
In Python, instead, we write it like below and the syntax is as follow:
for variable_name in range(start, stop, step)
- start: Optional. An integer number specifying at which position to start. Default is 0
- stop: An integer number specifying at which position to end.
- step: Optional. An integer number specifying the incrementation. Default is 1
INCREMENTED FOR LOOP 0 1 2 3 4 DECREMENTED FOR LOOP 4 3 2 1 0
Output-1: INCREMENTED FOR LOOP 0 1 2 3 4 Output-2: DECREMENTED FOR LOOP 4 3 2 1 0
