参照小甲鱼零基础学习python课后作业

1.输入密码

1.passwordbox的使用 passwordbox(msg, title,default=’默认的密码’, image=None)

import easygui as g
def passwordbox(msg, title):
    msg = g.passwordbox(msg, title,default='默认的密码', image=None)
    print(msg) # 默认的密码
passwordbox('content', 'title')

2.multpasswordbox的使用multpasswordbox(msg, title, fields, values)

import easygui as g
def multpasswordbox(msg, title, fields, values):

    print(msg) # ['张三', '123456']
fields = ('用户名','密码')
values = ('张三', '123456')
multpasswordbox('输入密码', '标题', fields, values)

    filepath = g.fileopenbox(boxcontent, boxtitle,default = 'D:/*.txt',filetypes='[*.txt]')
    file = open(filepath)
    filetext = file.read()
    texttitle = '文件标题'
    texttip = filepath + ' 的内容为：'
    boxtext = g.textbox(texttip,texttitle,text=filetext,codebox=0)
    if filetext != boxtext[:-1]:
        btn = ('覆盖保存','放弃保存','另存为...')
        choice = g.buttonbox('文件内容发生改变了，请选择如下操作：','警告',btn)
        if choice == '覆盖保存':
            with open(filepath,'w') as oldfile:
                oldfile.write(boxtext[:-1])
                oldfile.close()
        if choice == '放弃保存':
            pass
        if choice == '另存为...':
            newfilepath = g.filesavebox(default='.txt')
            newfile = open(newfilepath,'w')
            newfile.write(boxtext[:-1])
            newfile.close()
readfileshoutext()

改变文件弹出选择

3.目录与文件

1.diropenbox选择目录的路径 diropenbox(msg, title, default = None)

import easygui as g
def diropenbox(msg, title):
    msg = g.diropenbox(msg, title, default = None)
    print(msg) # F:\android_doc 目录地址
diropenbox('目录', '标题')

2.fileopenbox 选择文件的路径 fileopenbox(msg, title, default = ‘*’,filetypes = None)

default = ‘D:/python/program/a.py’ 表示D盘program下以a开头.py结尾的所有文件
default = ‘ * ‘ 表示所有文件

filetypes = [‘*.py’] 显示以.py结尾的文件
filetypes = None 显示所有文件

def fileopenbox(msg, title):
    msg = g.fileopenbox(msg, title, default = '*',filetypes = None)
    print(msg) # D:\python\program\b.py 文件地址
fileopenbox('选择文件', '标题')

3.filesavebox 选择保存文件的路径 filesavebox(msg, title, default = filename,filetypes = None)

default 文件的名字

    filecontent = open(filepath,'w')
    filecontent.write(filetext)
    filecontent.close()
    print(filepath) # D:\python\program\a.txt
filename = 'a.txt'
filetext = '这是一个测试文件的内容'
filesavebox(filetext,filename, '选择目录保存文件', '标题')

        para.filename = filename
        para.restore()
settings = Settings('D:/seting.txt')
settings.user = '张三'
settings.age = str(20)
settings.store()
a = open('D:/seting.txt','rb')
print(a.read())
