不可调用的字符串对象

Question

def power(num,div):
    incre =0 
    while(num%div == 0):
        num = num/div
        incre +=1
    return incre
test_case = int(raw_input())

lim = 0

while lim  < test_case:
    power = (raw_input())
    x = power.split()
    a = int(x[0])
    b = int(x[1])
    lim +=1
print power(a,b)

Python曾经正常工作,直到我遇到此错误.

Answer 1

raw_input总是返回一个字符串对象.因此,这一行:

power = (raw_input())

做power一个字符串.此外,当发生这种情况时,它会覆盖您的功能power.

当你到达这一点时:

print power(a,b)

power 是一个字符串,你试图像调用函数一样调用它时会出错.

要解决此问题,请重命名函数或字符串.他们俩都无法命名power.
