Python用tkinter做一个记事本程序。
用with 打开一个不存在的文件不会崩溃，简化了劳动。
还遇到一个问题，给窗口设置大小后，文本框和按钮就不出现了，不知道各位大佬有没有知道的。
代码如下：
#类似记事本小程序，可以打开文件，编辑，保存。
from tkinter import *
from tkinter.scrolledtext import ScrolledText
def Open():
with open(l.get()) as file:
contents.delete(1.0, END)
contents.insert(INSERT, file.read())
def Save():
with open(l.get(), w) as file:
file.write(contents.get(1.0, END))
win = Tk()
win.title(记事本)
#win.geometry(500x300)
contents = ScrolledText()
contents.pack(side=BOTTOM, expand=True, fill=BOTH)
l = Entry(win,show=None,width = 70)
#l.place(x=0,y=0)
l.pack(side = LEFT)
#filename = Entry()
#filename.pack(side=LEFT, expand=True, fill=X)
b1 = Button(win,text = Open,command = Open)
b2 = Button(win,text = Save,command = Save)
b1.pack(side = LEFT)
b2.pack(side = LEFT)
win.mainloop()
