TypeError参数过多 [英] TypeError Too many Arguments

问题描述

运行此代码时，出现错误，即第8行中的参数过多.我不确定如何修复它.

When running this code it appears with an error that there are too many arguments in line 8. I'm unsure on how to fix it.

#Defining a function to raise the first to the power of the second.
def power_value(x,y):
    return x**y

##Testing 'power_value' function
#Getting the users inputs
x = int(input("What is the first number?\n"))
y = int(input("What power would you like to raise",x,"to?\n"))

#Printing the result
print (x,"to the power of",y,"is:",power_value(x,y))

导致TypeError ...

Resulting in a TypeError...

     Traceback (most recent call last):
  File "C:\[bla location]", line 8, in <module>
    y = int(input("What power would you like to raise",x,"to?\n"))
TypeError: input expected at most 1 arguments, got 3

推荐答案

问题是python input()函数仅准备接受一个参数-提示字符串，但您传入了三个.要解决此问题，您只需要将所有三个部分组合为一个即可.

The issue is that the python input() function was only ready to accept one parameter - the prompt string, but you passed in three. To solve this issue, you just need to combine all three pieces into one.

您可以使用%运算符设置字符串格式:

You can use the % operator to format string:

y = int(input("What power would you like to raise %d to?\n" %x,))

或使用新方法:

y = int(input("What power would you like to raise {0} to?\n".format(x)))
