※ 引述《azulazure (独在异乡为异客)》之铭言： : I'm writing a python script about "split" function, : trying to use space to split a string. : It should work the same way as the built-in split function. : For example, "This is a sentence" should have the output : ['This', 'is', 'a', 'sentence'] : This the is script I have so far, but it won't give me the last word : in the sentence. If anyone knows how to fix it, I'll appreciate it very much. : ... if x not in " ": : ... word = word + x : ... else: : ... output.append(word) : ... word = " " : ... : ['This', ' is', ' a'] : I guess it's because there's only three space between the words so I get this : output, but this the the closest I can get. : I have to admit that this is my homework, but I've been working on it for : three days. I hope I can get some feedback on it. : By the way, I just had one lesson on python. I don't know many of the commands : yet (as you can see from this simple script). I'd appreciate it if you can : use simple language to fix this script. : Sorry I have to type in English. I have no access to Chinese now. inpu = "This is a sentence" word = "" output = [] for x in inpu: if x not in " ": word = word + x else: output.append(word) word = " " output.append(word) ^^^^^^^^^^^^^^^^^^^^^^^^^^ <-- you JUST need add this line or you can try this : inpu = "This is a sentence" word = "" output = [] for x in inpu + ' ': <-- add a space in the end of input sentence if x not in " ": word = word + x else: output.append(word) word = " " --
