if got the data then stop the loop in python code example

Example 1: python exit for loop

# python 3

for x in range(1, 10):
    print(x)
    if x == 4:
        break
# prints 1 to 4

Example 2: python continue vs pass

Yes, there is a difference. 

continue forces the loop to start at the next iteration 
while pass means "there is no code to execute here" 
and will continue through the remainder or the loop body. 
continue will jump back to the top of the loop. 
pass will continue processing.
