While loop

Why would there be loops like this statement?

To give a simple example: we want to calculate the number of even numbers within 0-100, and this time we need to loop this statement

Then one might say, "What 0+2+4+.......+98 can be calculated?"

Suddenly our condition changed: Calculate the number of even numbers within 0-10000000 and

It can be imagined that this is how a workload, the cycle is just to solve this problem.

Figure:

The representation of a while loop in Python is like.

Grammatical form:

 while Loop condition: Loop body (code block) loop Body (code block)     Loop Body (code block)             ...

eg

# calculates an even number of 100 and count= = 0                # Total  while Count <:       If count%2==0:    # to determine if an even        sum+=count    # is an even number added    count+=1            # Count plus one
