我的问题是不同的,因为答案传达了更深层次的问题,即简洁的代码与像森林一样的变量。我相信我应该得到声誉点,指出简洁缩短的变量代码的清晰度是为了找到逻辑问题。
我正在开发Dataquest教程数据Python btw 的好站点,并且遇到此字符串清理代码的问题。清理过的字符串与原始字符串完全一致,没有解析出来。
这里是代码,我尽量使其尽可能简洁:
ss = open('story.txt', 'r').read()
cc = [",", ".", ";", "\n", "'"]
print(ss + "\n\n\n")
cleaned_story = ""
def clean_text(x, y):
cs = x
for e in y:
cs.replace(e, "")
cs = cs.lower()
return cs
cleaned_story = clean_text(ss, cc)
print(cleaned_story)
print(type(cleaned_story)) #this is just for weird test

没关系。我发现了这个问题。使代码更简洁帮助我立即看到错误。在使用replace方法后,我忘了将<div id="assistenzen">
<form>
<select v-model="assistenz" multiple>
<option v-for="option in options" v-bind:value="option">
{{ option.text }}
</option>
</select>
<ul>
<li v-for="assi in assistenz">{{assi.text}}
<input v-model="assi.prozent">
{{assi.prozent}}
</li>
</ul>
</form>
</div>
<script>
var assistenz = new Vue({
el: '#assistenzen',
data: {
assistenz: 'keine Assistenz',
options: [
{ text: 'One', value: 'A', prozent: '0' },
{ text: 'Two', value: 'B', prozent: '0' },
{ text: 'Three', value: 'C', prozent: '0' }
]
},
});
assistenz.config.devtools = true
</script>
变量赋给自己。
我非常喜欢Python!
感谢StackOverflow。你是上帝!

看起来你正在调用函数.replace(),它返回字符串的修改版本,但没有为返回值赋值。我将行改为
cs = cs.replace(e, "")
它工作正常。
ss = "this text, it is... a test;"
cc = [",", ".", ";", "\n", "'"]
print(ss + "\n\n\n")
cleaned_story = ""
def clean_text(x, y):
cs = x
for e in y:
cs = cs.replace(e, "")
cs = cs.lower()
return cs
cleaned_story = clean_text(ss, cc)
print(cleaned_story)
print(type(cleaned_story)) #this is just for weird test
