检查 Python 中的数字是否相同

Question

How to check if a number has same digit in Python

For example:

check(111) --> True

check(22) --> True

check(111) --> True

check(45) --> False

Answer 1

Are you expecting an answer like this? It will return True if all the digits are same else False.

What I am doing in this answer is, I am taking the first digit then I am multiplying the string form of the digit times the length of the string and using an If statement to check whether they match or not.

def check(n):
    if str(n) == str(n)[0] * len(str(n)):
        return True
    else:
        return False


print(check(45))
