在Python中,ifexists是一个用于检查某个变量或对象是否存在的函数。它返回一个布尔值,如果变量存在,则返回True;否则,返回False。 语法 ifexists函数的语法如下所示: ifexists(variable) 1. 其中,variable是要检查的变量或对象。 使用ifeixsts的例子 下面是一些使用ifexists函数的例子,以帮助你更好地理解它的用法。
Python Copy In this example, we’re importing theosmodule and using theexists()function from theos.pathmodule. We pass the name of the file we’re checking for as a string argument to theexists()function. If the file exists, the function returnsTrue, and if it doesn’t, it returnsFalse...
