Python has a really sophisticated way of handling iterations. The only thing it does not have “GOTO Labels” which I think is good.

Let us compare the three common ways of iterations in Python: While, For and Map by the way of an example. Imagine that you have a list of numbers and you would like to find the square of each number.

```
nums = [1,2,3,5,10]
result = []
for num in nums:
result.append(num*num)
print(result)
```

It would print `[1, 4, 9, 25, 100]`
