Yes, it runs for exactly eight times and stops.💡 Explanation:Iteration over a dictionary that you edit at the same time is not supported. It runs eight times because that's the point at which the dictionary resizes to hold more keys (we have eight deletion entries, so a resize is ...
Keyboard from ahk import AHK ahk = AHK() ahk.type('hello, world!') # Send keys, as if typed (performs string escapes for you) ahk.send_input('Hello, {U+1F30E}{!}') # Like AHK SendInput # Unlike `type`, control sequences must be escaped manually. # For example the characters ...
在键盘事件函数中,可以使用key == keys.LEFT判断left键是否按下; 在键盘事件函数以外,比如update函数中,可以通过keyboard[keys.LEFT]判断left是否按下。 fromcpgzeroimport*alien=Actor("alien")defupdate():ifkeyboard[keys.LEFT]:alien.x-=10elifkeyboard[keys.RIGHT]:alien.x+=10...
