stripped_line.split()是什么意思

`stripped_line.split()` 是一个Python操作，通常用于字符串处理。它涉及到两个步骤：

1. `strip()`：这个方法是针对字符串的，作用是移除字符串两端的空白字符（包括空格、制表符、换行符等），返回一个新的字符串。如果原始字符串`stripped_line`已经没有前导或尾随空白，则此步骤可以跳过。

2. `split()`：在`strip()`之后，`split()`方法会被应用到结果上。这一步会按照指定的分隔符（默认为空格或连续的空白字符）将字符串分割成一个列表。每个分隔符所在的位置都会成为列表的一个边界，分隔后的部分将成为列表中的新元素。

例如，假设你有一个包含多个词的字符串，且字符串首尾可能有不必要的空白，那么 `stripped_line.split()` 就可以方便地拆分成单词列表，去除多余的空白影响。

完整的代码示例可能是这样的：

line = "  hello world!   "
stripped_line = line.strip()
words = stripped_line.split()

print(words)  # 输出：['hello', 'world!']

import csv with open(r'C:\Users\Administrator\Downloads\Shanghai_Dialect_Scripted_Speech_Corpus_Daily_Use_Sentence') as infile: stripped = (line.strip() for line in infile) lines = (line.split(",") for line in stripped if line) with open('output.csv', 'w') as outfile: writer = csv.writer(outfile) writer.writerows(lines) SyntaxError: invalid syntax

这段代码存在一个语法错误，需要加上文件的读取模式。应该修改为：

import csv
with open(r'C:\Users\Administrator\Downloads\Shanghai_Dialect_Scripted_Speech_Corpus_Daily_Use_Sentence.csv', 'r') as infile:
    stripped = (line.strip() for line in infile)
    lines = (line.split(",") for line in stripped if line)
    with open('output.csv', 'w') as outfile:
        writer = csv.writer(outfile)
        writer.writerows(lines)

这样代码就可以正确读取文件，并将数据写入一个名为 `output.csv` 的 CSV 文件中。

key, value = line.strip().split(': ')

As an AI language model, I do not have context for this line of code. However, I can explain what it does in general terms.

This line of code is used to split a string into two parts, based on a delimiter (in this case, ': '). The string is first stripped of any whitespace at the beginning or end using the `.strip()` method. Then, the `split()` method is used to split the string into two parts - the part before the delimiter, and the part after the delimiter. These two parts are assigned to the variables `key` and `value`, respectively.

For example, if the original string was "name: John", then `key` would be assigned the string "name" and `value` would be assigned the string "John".
