自娱自乐一

自娱自乐系列一：

为了过年提前回家，周六过来加班调休，又不大想干活，就想着捣鼓点自娱自乐的东西：

输入年龄判断是否有投票资格：

def judge_age():

    while True:
        try:
            age = int(input("\nPlease enter your age："))
        except ValueError:
            print("Sorry,I can't understand what you entered.Please enter a correct number.")
            continue
        else:
            break
    if age >= 18:
        print("You are able to vote in the United States!")
    else:
        print("You are too young to vote in the United States!")

if __name__ == '__main__':
    judge_age()

判断输入的正整数:

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

def get_non_negative_int(prompt):
    try:
        value = int(input(prompt))
    except ValueError:
        print("Sorry,I can't understand that.")
        return get_non_negative_int(prompt)

    if value < 0:
        print("Sorry,your response must not be negative.")
        return get_non_negative_int(prompt)
    else:
        return value

def guess_number():
    number = get_non_negative_int("Please enter a number to guess: (only positive integer can work,thanks!)")
    while True:
        guess = get_non_negative_int("guess the number.")
        if guess > number:
            print("You could enter a lower one.")
        elif guess < number:
            print("I think it could be higher.")
        else:
            print("Congratulations! You got it!")
            break


if __name__ == '__main__':
    guess_number()

纯属自娱自乐，毫无技术含量 Thanks?(?ω?)?

顺便贴个常识坑：

文件夹不能取名是**code**，否则pycharm的debug模式会报错！！！（stackoverflow真是个好网站！什么坑都能找到填的办法。。）
原因：
debug模式会引个包：

from code import InteractiveConsole 

工程中有code文件夹，会找不到debug需要的方法
