小甲鱼《零基础学习Python》课后笔记（三十五）：图形用户界面入门——EasyGui

动动手
0.先练练手，把我们的刚开始的那个猜数字小游戏加上界面吧?

import easygui as g
import random

g.msgbox('嗨，欢迎进入第一个界面小游戏！')
secret = random.randint(1,10)

msg = "猜猜我心中的数字是什么(0~10)："
title = "数字小游戏"
guess = g.integerbox(msg, title, lowerbound = 0, upperbound = 10)

while True:
    if guess == secret:
	    g.msgbox('你是我肚里的蛔虫吗！')
	    break
    else:
	    if guess > secret:
	    	g.msgbox('猜大了呀，再试试')
	    else:
	    	g.msgbox('猜小了呀，再试试')
	    guess = g.integerbox(msg, title, lowerbound = 0, upperbound = 10)

g.msgbox('游戏结束，不玩啦！')

1.实现一个用于登记用户账号信息的界面（如果是带*号的必填项，要求一定要有输入并且不能是空格）。

from easygui import *
msg = "输入你的个人信息"
title = "登录界面"
fieldNames = ["账号名*","密码*","地址","联系电话*","邮箱地址"]
fieldValues = []  # 创建一个空列表存放账号信息
fieldValues = multenterbox(msg,title, fieldNames)

# 确保带*号的信息不为空
while 1:
    if fieldValues == None: 
    	break
    errmsg = ""
    for i in range(len(fieldNames)):
      if (fieldValues[i].strip() == "") and (fieldNames[i][-1] == "*"):
        errmsg = errmsg + ('"%s" 是必填项.\n\n' % fieldNames[i])
    if errmsg == "": 
    	break 
    fieldValues = multenterbox(errmsg, title, fieldNames, fieldValues)
print("个人信息:", fieldValues)

2.提供一个文件浏览框，让用户选择需要打开的文本文件，打开并显示文件内容。

import easygui as g  
import os  
	  
file_path = g.fileopenbox(default = "*.txt")  
	  
with open(file_path) as f:  
	title = os.path.basename(file_path)  
	msg = "文件【%s】的内容如下：" %title  
	text = f.read()  
	g.textbox(msg, title, text)  

3.在上一题的基础上增强功能：当用户点击“OK”按钮的时候，比较当前文件是否修改过，如果修改过，则提示“覆盖保存”、“放弃保存”或“另存为…”并实现相应的功能。

import easygui as g  
import os  
  
file_path = g.fileopenbox(default = "*.txt")  
 
with open(file_path) as old_file:  
	title = os.path.basename(file_path)  
	msg = "文件【%s】的内容如下：" %title  
	text = old_file.read()  
	text_after = g.textbox(msg, title, text) 

if text != text_after[:-1]:
	#textbox的返回值会追加一个换行符
	choice = g.buttonbox("文件已修改，请做出选择：", "警告", ("覆盖保存", "放弃保存", "另存为…"))
	if choice == "覆盖保存":
		with open(file_path, "w") as old_file:
			old_file.write(text_after[:-1])
	if choice == "放弃保存":
		pass
	if choice == "另存为…":
		another_path = g.filesavebox(default = ".txt")
		if os.path.splitext(another_path)[1] != '.txt':
			another_path += '.txt'
		with open(another_path, "w") as new_file:
			new_file.write(text_after[:-1])

4.写一个程序统计你当前代码量的总和，并显示离十万行代码量还有多远？
要求一：递归搜索各个文件夹
要求二：显示各个类型的源文件和源代码数量
要求三：显示总行数与百分比

import easygui as g
import os


def show_result(start_dir):
	lines = 0
	total = 0
	text = ""

	for i in source_list:
		lines = source_list[i]
		total += lines
		text += "【%s】源文件 %d 个，源代码 %d 行\n" % (i, file_list[i], lines)
	title = '统计结果'
	msg1 = '您目前共写了 %d 行代码，完成进度：%.2f %%\n离10万行代码还差 %d 行，请继续努力！' % (total, total/1000, 100000 - total)
	msg2 = '您目前共写了 %d 行代码，完成进度：%.2f %%\n超额完成 %d 行，真棒！' % (total,  total/1000, total - 100000)
	if total <= 100000:
		g.textbox(msg1, title, text)
	else:
		g.textbox(msg2, title, text)

def calc_code(file_name):
	lines = 0
	with open(file_name) as f:
		print('正在分析文件：%s ...' % file_name)
		try:
			for each_line in f:
				lines += 1
		except UnicodeDecodeError:
			pass 
	return lines

def search_file(start_dir):
	os.chdir(start_dir)

	for each_file in os.listdir(os.curdir):
		ext = os.path.splitext(each_file)[1]
		if ext in target:
			lines = calc_code(each_file)
			try:
				file_list[ext] += 1
			except KeyError:
				file_list[ext] = 1

			try:
				source_list[ext] += lines
			except KeyError:
				source_list[ext] = lines
		if os.path.isdir(each_file):
			search_file(each_file)
			os.chdir(os.pardir)

target = ['.c', '.cpp', '.py', '.cc', '.java','.pas', '.asm']
file_list = {}
source_list = {}

g.msgbox("请打开您存放所有代码的文件夹......", "统计代码量")
path = g.diropenbox("请选择你的代码库：")

search_file(path)
show_result(path)
