Example: Print first 10 numbers using a for loop Here we used the range() function to generate integers from 0 to 9 Next, we used the for loop to iterate over the numbers produced by the range() function In the body of a loop, we printed the current number. for num in range(10...
The loop ends after the body of the loop is executed for the last item. Indentation in Loop In Python, we use indentation (spaces at the beginning of a line) to define a block of code, such as the body of a loop. For example, languages = ['Swift', 'Python', 'Go'] # start of...
A range for-loop goes from a low numerical value to a high numerical value, like: for i in range(0,3): print i It prints the following range values: 0 1 2 A for-each loop goes from the first to the last item while ignoring indexes, like: list = ['a','b','c'] for i in...

In this new loop implementation, you’re using a new list to store the result. Because of this, you don’t have to remove items anymore. You add the square values to the end of the new list using the .append() method. Python doesn’t allow you to add or remove items from a dicti...

This small script will count from 0 to 9. The i = i + 1 adds 1 to the i value for every time it runs. i = 0 while i < 10: print i i = i + 1 Eternal Loops Be careful to not make an eternal loop in Python, which is when the loop continues until you press Ctrl+C. Mak...
