causes and solutions

reference the blog https://blog.csdn.net/feng2147685/article/details/86494905, and https://www.cnblogs.com/Jimc/p/9606112.html

is a Python string concatenation problem;

if __name__ == '__main__':
    num1 = int(input("Please enter a positive integer: "))
    num2 = int(input("Please enter a positive integer. "))
    print("i%d" % (gcd(num1, num2)) + "hahahha")
