startswith() 方法返回一个布尔值,如果 base_string 以prefix 开始,则返回 True,否则返回 False。根据这个返回值,我们可以输出相应的检查结果。 此外,startswith() 方法还可以接受可选的 start 和end 参数,用于指定检查的范围。例如: python # 检查从索引2开始到索引10结束的子串是否以 "lo" 开始 if base_...

We can do this by using python startswith() method. See example below:# string one string1 = "This is our school" # string two string2 = "My name is khan" # string three string3 = "+996-3028374" # check string print(string1.startswith("This")) print(string2.startswith("my")...

we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with each of the strings joined by the initial string. Let’s check its functionality with one simple...
