How to print all pronic numbers between 1 and 100 in Python

Answer 1

# A pronic number is a number which is the product of two consecutive integers
# 42 = 6 * 7 -> yes 6 and 7 is consecutive integers
# 45 = 5 * 9 -> no 5 and 9 is not consecutive integers
 
def isPronicNumber(num) :
    for i in range(num) :
        if ((i * (i + 1)) == num) :
            return True
    return False
     

for i in range(100) :  
    if (isPronicNumber(i)) :
        print(i);
