Question

有没有办法在输入python 3终端时将文本转换为点我的代码是：

[........
user = input('Enter Your UserName:')
pass = input('Enter Your Password:')
........]

我知道模块getpass。但它不在终端工作，它会发出警告：

Warning (from warnings module):
return fallback_getpass(prompt, stream)
GetPassWarning: Can not control echo on the terminal.
Warning: Password input may be echoed.

如果它可以在没有警告的情况下工作并隐藏文字，请告诉我有没有其他类似的东西：

import sys
shell = sys.stdout.shell
shell.show input as '0';
....

我正在创建一个脚本，要求用户提供密码，但如果在输入时显示密码则看起来很糟糕我在这里希望你能帮助我如果您想了解更多信息，我愿意为您提供感谢....

您无法在Python IDLE内使用getpass。

同样尝试重定向 stdout 等操作会导致在 IDLE 中重启shell：

import sys
import os
import getpass

sys.stdout = os.devnull
getpass.getpass()

== RESTART: Shell ==

也许您可以使用tkinter对话框窗口提示用户输入密码：

# import tkinter (a crossplatform GUI)
import tkinter

# import a simple dialog form with a label and a button
# so you don't have to build one yourself
import tkinter.simpledialog

# create an empty main window for GUI,
# without it you will get an error:
# AttributeError: 'NoneType' object has no attribute 'winfo_viewable'
tk_root = tkinter.Tk()

# you don't really need to show it, so hide it immediately
tk_root.withdraw()

# create a dialog window with title 'Password'
# and a text label 'Enter Your Password:'
# also hide typed password with *
passwd = tkinter.simpledialog.askstring('Password','Enter Your Password:', show='*')

只需将其保存为函数：

def get_pass():
    import tkinter
    import tkinter.simpledialog
    tk_root = tkinter.Tk()
    tk_root.withdraw()
    return tkinter.simpledialog.askstring('Password','Enter Your Password:', show='*')

并使用get_pass()代替getpass()。

分别使用密码输入和tkinter是一个坏主意我创建了一个只有密码的用户名和密码：

from tkinter import * #(tkinter (A cross-platform GUI)

top = Tk()
def callback(): #what to do after button(Submit) pressed
    print(E2.get()) #printing first input
    print(E1.get()) #printing second input
    top.destroy() #exiting tkinter
top.title('Login')
L1 = Label(top, text="User Name")
L1.grid(row=0, column=0) #setting up position for user name field
E2 = Entry(top, bd = 5)
E2.grid(row=0, column=1)

L1 = Label(top, text="Password")  # text for second name,currently Password
L1.grid(row=1, column=0) #setting up position for password field
E1 = Entry(top, bd = 5,show='*') #hidding the text with *
E1.grid(row=1, column=1)
MyButton1 = Button(top, text="Submit", width=10, command=callback) # button named submit
# 'command=callback ' the command you want to do|we have created a function callback

MyButton1.grid(row=3, column=1) # position for button

top.mainloop()

希望这对你有所帮助 Getpass 不适用于 IDLE
