Question

代码：

def power(base,exponent):  
  result = base**exponent
  print "%d to the power of %d is %d." % (base, exponent, result)

n=raw_input("Enter a number whose power you wish to calculate:")
p=raw_input("Enter the power:")
power(n,p)

执行请帮助时出现一些unicode错误

Answer 1

raw_input返回字符串。你必须将它转换为整数，因为你的函数找到一个数字的力量。

def power(base,exponent):  
    result = base**exponent
    print "%d to the power of %d is %d." % (base, exponent, result)

n=int(raw_input("Enter a number whose power you wish to calculate:"))
p=int(raw_input("Enter the power:"))
power(n,p)

Answer 2

您也可以使用它来确保在插入非数字时不会出错：

def power(base,exponent):  
    result = base**exponent
    print "%d to the power of %d is %d." % (base, exponent, result)

def int_input(message):
    input_value = raw_input(message)
    if input_value.isdigit():
        return int(input_value)
    print "This is not a Number."
    return int_input(message)

n = int_input("Enter a number whose power you wish to calculate:")
p = int_input("Enter the power:")
power(n, p)

通过函数unicode错误在python中传递变量
