Python 任务，“is_power_of 函数”[关闭]

  • 772

我正在用python解决一个问题，我不明白拼写和问题本身。任务是英文的，翻译者不知何故没有清醒地翻译，或者在我看来，任务本身：

填空使 is_power_of 函数返回数字是否是给定基数的幂。注意：base 假定为正数。提示：对于返回布尔值的函数，您可以返回比较结果。

这是向我提出的代码（所有 __ 值得放东西的地方）：

def is_power_of(number, base):
    # Base case: when number is smaller than base.
    if number < base:
       # If number is equal to 1, it's a power (base**0).
       return __

    # Recursive case: keep dividing number by base.
    return is_power_of(__, ___)

print(is_power_of(8,2)) # Should be True
print(is_power_of(64,4)) # Should be True
print(is_power_of(70,10)) # Should be False

我不明白该怎么做，请帮忙

    试试这样：

    def is_power_of(number, base):
    # Base case: when number is smaller than base.
    if number < base:
        # If number is equal to 1, it's a power (base**0).
        return number==1

    # Recursive case: keep dividing number by base.
    return is_power_of(number // base, base)

print(is_power_of(8, 2))   # Should be True
print(is_power_of(64, 4))  # Should be True
print(is_power_of(70, 10)) # Should be False
