Question

在我的程序中，我需要进行简单的数学计算，但是我的变量在str处定义，因此我需要对int进行计算以求和和。

例如：

当age = 40时，我得到404040404040（是40的6倍）被读取为“ str”之类的res，我需要“ int”。

def check_age(age):
    age = int(age)
    return 30 * 6 if age >= 30 else 0


def just_married():
    sum_married = 0
    woman_age = int(input("Please enter the wife age [we know that is not ok ask woman about she's age] : ").strip())
    sum_married = sum_married + check_age(woman_age)
    husband = int(input("Please enter the husband age : ").strip())
    sum_married = sum_married + check_age(husband)
    return int(sum_married)


def children_age(number_of_children):
    sum_children = number_of_children*50
    return int(sum_children)


def work_hard():
    print("for WIFE - Are you working part-time (0.5) or full-time (1)? : ")
    wife_work = input()
    print("for HUSBAND = Are you working part-time (0.5) or full-time (1)? : ")
    husband_work = input()
    sum_work = (wife_work+husband_work)*75
    return int(sum_work)


def main():
    sum_func = 0
    print("The following is a program aimed at examining eligibility conditions "
          "for participation in the tender Housing for the occupant.")
    sum_func += just_married()
    print("How many children over the age of 18 do you have? : ")
    children = input()
    sum_func += children_age(children)
    sum_func += work_hard()
    program_number = 599
    if sum_func > program_number:
        print("you got : " + str(sum_func) + " points ")
    else:
        print("sorry, but you need " + str(program_number-sum_func) + " point to join the program. try next time.")


main()

编辑：我编辑代码，并在功能“ check_age”处进行了新更改，然后更新了完整代码。

这是输入：

The following is a program aimed at examining eligibility conditions for participation in the tender Housing for the occupant.
Please enter the wife age [we know that is not ok ask woman about she's age] : 40
Please enter the husband age : 50
How many children over the age of 18 do you have? : 
4
for WIFE - Are you working part-time (0.5) or full-time (1)? : 
1
for HUSBAND = Are you working part-time (0.5) or full-time (1)? : 
1
you got : 111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111155555555555555555555555555555555555555555555555915 points

在您的函数check_age中：

def check_age(age):
    age = int(age)
    return 30 * 6 if age >= 30 else 0

另外，请考虑更改以下行：

print("Please enter the wife age [we know that is not ok ask woman about she's age] : ")
woman_age = input(int)

对此：

woman_age = int(input("Please enter the wife age [we know that is not ok ask woman about she's age] : ").strip())

说明：

input接收字符串，将其打印并等待用户输入。
str.strip删除尾随空格
int将变量转换为整数

清理输入内容后，可以在check_age中删除对int的显式转换：

def check_age(age):
    return 30 * 6 if age >= 30 else 0

[编辑]还有一些建议：

创建一个接受文本的函数sanitize_input，要求输入广告返回一个整数。然后在任何地方使用它来替换{{1}} ... print
创建有意义的逻辑块：例如，main函数包含所有打印到屏幕上的文本，并存储所有输入以备后用。然后，仅在input之类的函数中处理变量，或者在所有函数中进行处理。如果这样做，对于您和对您有帮助的人，您的代码将更容易理解，并且更不易出错

在尝试进行任何计算之前，必须先完成字符串->数字转换，在module.exports.shipments = async (event) => { const axios = require("axios"); let data = JSON.parse(event.body); let url = data.apiURL + "/api/1.1/wf/bulkshipments"; let patchURL = data.apiURL + "/api/1.1/obj/company/" + data.companyID; let good = []; let bad = []; let promises = data.shipments.map(item => axios.post(url, { batchID: data.batchID, companyID: data.companyID, shipment: item }) //.then( res => good.push({"Order Reference": item.order_reference, "result": res.data})) //.catch( error => bad.push({"Order Reference": item.order_reference, "result": error.response.data})) ); await Promise.all(promises); return { statusCode: 200, body: JSON.stringify({ message: 'success', totalShipments: data.shipments.length, created: good.length, errors: bad.length, result: {"completed": good, "failed": bad} }, null, 2), }; };时为时已晚，因为已经发生了奇怪的事情。记住/了解到Python可以添加字符串（许多语言都通用，return在其他各种语言中也都是"1"+"1"），此外，它还可以将它们与整数{ {1}}是"11"。
如果您假设用户输入正确，那么最简单的方法就是在"1"*5行中进行转换，这已经发生在"11111"中，但在其他地方则没有。
当然，请记住，当您希望输入input之类的内容时，应将其转换为just_married。

变量不会更改为“ int”-停留在“ str”
