python中的基本计算器程序 [英] Basic calculator program in python

问题描述

我只是用python写了一个简单的计算器脚本，通常python默认会识别（-）减号（*）乘号（/）分隔符号，但考虑到此脚本，它无法识别符号。请留下您的评论以使我明白...

I just wrote a simple calculator script in python, generally python should recognize the (-)minus,(*)multiplication,(/)divide sign by default but while considering this script it's fails to identify the signs. please leave your comments to clear me...

#! /usr/bin/python

print("1: ADDITION")
print("2: SUBTRACTION")
print("3: MULTIPLICATION")
print("4: DIVISION")

CHOICE = raw_input("Enter the Numbers:")

if CHOICE == "1":
    a = raw_input("Enter the value of a:")
    b = raw_input("Enter the value of b:")
    c = a + b
    print c

elif CHOICE == "2":
    a = raw_input("Enter the value of a:")
    b = raw_input("Enter the value of b:")
    c = a - b
    print c

elif CHOICE == "3":
    a = raw_input("Enter the value of a:")
    b = raw_input("Enter the value of b:")
    c = a * b
    print c

elif CHOICE == "4":
    a = raw_input("Enter the value of a:")
    b = raw_input("Enter the value of b:")
    c = a / b
    print c

else: 
 print "Invalid Number"
 print "\n"

推荐答案

您需要更改输入内容，串s为整数或浮点数。由于存在除法，因此最好将其更改为浮点数。

You need to change your inputs, strings to integer or float. Since, there is division you are better change it to float.

a=int(raw_input("Enter the value of a:"))
a=float(raw_input("Enter the value of a:"))
