Python csv 字数到列

Question

抱歉，我已经从头开始尝试了四天。 我正在尝试使用 csv 并添加一个带有字数的列。 每行都有自己的计数（特别是第 10 列）。 我尝试了多种方法、库和 pandas。 我还与知道如何编程的家人一起工作，他们似乎很难过。 我会尽我所能得到的帮助。 语言是 python。

import csv

with open('C:\\Users\\Admin\\Desktop\\Big data\\test.csv','r') as csvinput:
    with open('C:\\Users\\Admin\\Desktop\\Big data\\testa.csv', 'w') as csvoutput:
    writer = csv.writer(csvoutput, lineterminator='\n')
    reader = csv.reader(csvinput)

    all = []
    row = next(reader)
    row.append('Wordcount')
    all.append(row)

    words = []
    for i in words:
        words.append(i)

    words_counted = []
    for i in words:
        x = words.count(i)
        words_counted.append((i,x))

    for row in reader:
        row.append(row[10])
        all.append(row)
        words = row[0].split(" ")

    writer.writerows(all)

我会给你一个如何做字数统计的示例代码：

import pandas as pd
a =  "This is a sample line"
b = "lets count the words for each line"
df = pd.DataFrame([a,b], columns=['col'])

东风：

col
0   This is a sample line
1   lets count the words for each line

---

df['totalwords'] = df['col'].str.split().str.len()

---

东风：

    col                                 totalwords
0   This is a sample line               5
1   lets count the words for each line  7
