Python basic keyboard operation

Python basic keyboard operation

1. Keyboard input

pyautogui.keyDown(): Simulate key press ;:
pyautogui.keyUp()Simulate key release
pyautogui.press();: # is to call keyDown() & keyUp() to simulate a key press;: The
pyautogui.typewrite('this',0.5)first parameter is the input content, and the second parameter is the interval time between each character;
pyautogui.typewrite(['T','h','i','s']):typewrite You can also pass in a single letter list;

For example:

pyautogui.keyDown('shift')    # 按下shift
pyautogui.press('4')    # 按下 4
pyautogui.keyUp('shift')   # 释放 shift

Output: $;

pyautogui.typewrite('$$$$', 0.5)

Slow output: $$$

2. Keyboard special keys

Sometimes we need to enter some special keys, such as the left arrow, which are represented by corresponding keyboard strings, for example:

pyautogui.typewrite(['T','i','s','left','left','h',])   # 输出：This

Explanation: The left here is the arrow to the left; there are many other keyboard strings, please refer to the following table:

Keyboard string	Description
enter (or return or \n)	Carriage return
esc	ESC
shiftleft, shiftright	Left and right SHIFT keys
altleft, altright	Left and right ALT keys
ctrlleft, ctrlright	Left and right CTRL keys
tab (\t)	TAB键
backspace, delete	BACKSPACE 、DELETE键
pageup, pagedown	PAGE UP 和 PAGE DOWN键
home, end	HOME and END keys
up, down, left,right	Arrow keys
f1, f2, f3 ... f12	F1…….F12 key
volumemute, volumedown,volumeup	The sound becomes louder and quieter (some keyboards do not)
pause	PAUSE key, pause key
capslock	CAPS LOCK key
numlock	NUM LOCK key
scrolllock	SCROLLLOCK key
insert	INSERT key
printscreen	PRINT SCREEN key
winleft, winright	Win 键 (windows)
command	command key (Mac OS X)
option	option（Mac OS X）

3. Shortcut keys

If we need to simulate the copy shortcut key ctrl+ c, if we use the previous method, the code is:

pyautogui.keyDown('ctrl')
pyautogui.keyDown('c')
pyautogui.keyUp('c')
pyautogui.keyUp('ctrl')

The order of pressing and releasing the shortcut keys is very important. At this time, we can use pyautogui.hotkey(). This function can accept multiple parameters, press them in the order in which they are passed in, and release them in the reverse order. The above shortcut key ctrl+ ccan change the code to:

pyautogui.hotkey('ctrl','c')

4. Prompt message box

1. Prompt Box/Warning Box

import pyautogui
a = pyautogui.alert(text='This is an alert box.', title='Test')
print(a)

The output is as follows: Click OK, the return value is'OK'

2. Select box

import pyautogui
a = pyautogui.confirm('选择一项', buttons=['A', 'B', 'C'])
print(a)

The output is as follows: Click the B option, the return value is'B'

3. Password input

import pyautogui

a = pyautogui.password('Enter password (text will be hidden)')
print(a)

The output is as follows: input the password, it will be displayed as cipher text, click OK, the return value is the value just entered

4. Normal input

import pyautogui

a = pyautogui.prompt('请输入一个数字：')
print(a)

The output is as follows: display as plain text, click OK, the return value is the value just entered;
