You can also determine the number of items in a list by using len. So you could use a while loop and a counter to loop or iterate over each item in the list. Because this operation is so common, Python provides for loops, which you can use to iterate over lists....
Also, we are going to use one of Python’s built-in functionrange(). This function is extensively used in loops to control the number of times the loop has to run. In simple words range is used to generate a sequence between the given values. For a better understanding of these Python...
We will cover python loops, python dictionaries, and basic python loop syntax. Understanding for loop in Python The for loop in Python is used to iterate over a sequence (like a list, tuple, or string) or other iterable objects. Iterating over a sequence means going through each element ...

This is the structure of a basic for loop in Python: for[Temporary variable]in[sequence]: [do something] The syntax is very specific therefore you should always follow this particular layout. The for loop must have a colon(:) after the sequence, and the statement under the loop must be ...

How To Make A While Loop in Python Now that you know what you need to construct a while loop, all that is left to do now is to look at a real-life example where the while loop is used before you start making exercises on your own! Consider the following example: # Take user input...
Python code of a for loop from 1 to 4: for i in range(5): # do something In C++: for(inti=0;i<5;i++){// do something} There is a huge difference here. In C++, we can control i in the loop. For example, for(inti=0;i<5;i++){i=5;cout<<"run once!"<<endl;} ...
