Answer 1

In documentation terminology, indentation means the space from margin to the begin of characters in a line.

Python uses indentation. In your code, While is a condition, all the block of code to be executed for true, must start at same position from the margin, must be farther away from margin than that of the condition.

I too faced this error.

Example:

if __name__ == '__main__':
    a = int(input())
    b = int(input())
    if a>=1 and a<=10000000000 and b>=1 and b<=10000000000:
    print(a+b)
    print(a-b)
    print(a*b)

will throw "IndentationError: expected an indented block (solution.py, line 5)"

Fix:

if __name__ == '__main__':
    a = int(input())
    b = int(input())
if a>=1 and a<=10000000000 and b>=1 and b<=10000000000:
    print(a+b)
    print(a-b)
    print(a*b)
