Question

我有一个像这种格式的txt文件：

Monday, Jul 24
8:45 apple 1    
school
ball
dog
8:50 poirot 2   
rouge
chien   
chat
8:55 football 3
asroma
juventus  
inter

如何将这些值放入csv而忽略第一行（7月24日星期一）并在每行中插入实际日期？我需要这种格式：

A1 Monday, Jul 24
B1:8:45 apple 1   B2:school B3:ball    B4:dog    B5:ACTUALLY DATE
C1:8:50 poirot 2  C2:rouge  C3:chien   C4:chat   C5:ACTUALLY DATE
etcetc..

所以我想把它们放在这种格式中。这是我的实际代码：

import urllib2
import unicodecsv as csv
import os
import sys
import io
import time
import datetime
import pandas as pd
from bs4 import BeautifulSoup
import sys
import re

#def to_2d(l,n):
#    return [l[i:i+n] for i in range(0, len(l), n)]

with open('air.txt', 'r') as f:
    x = f.read()
print x

req_text = x.split('Test')[1: -1]

data = []
for text in req_text:
    text = text.split('\n', 1)[1]
    for line in text.strip().splitlines():
        data.append([line])

#maindatatable = to_2d(data, 4)

with open('output.csv', "wb") as f:
    output = csv.writer(f, delimiter=';',quotechar = '"', quoting=csv.QUOTE_NONNUMERIC, encoding='latin-1')
    output.writerows(data)

f.close()

我尝试使用to_2d（l，n），但它不起作用，任何想法我怎么能用实际日期达到这种格式？ [Python 2.7]

更新了代码，但仍无效：

import urllib2
import unicodecsv as csv
import os
import sys
import io
import time
import datetime
import pandas as pd
from bs4 import BeautifulSoup
import sys
import re

def to_2d(l,n):
    return [l[i:i+n] for i in range(0, len(l), n)]
 
with open('air.txt', 'r') as f:
    x = f.read()
print x

req_text = x.split('Load')[1: -1]

data = []
for text in req_text:
    text = text.split('\n', 1)[1]
    for line in text.strip().splitlines():
        data.append([line])

#maindatatable = to_2d(data, 4)

from string import ascii_uppercase as LETTERS
with open('air.txt') as f, open('output.csv', 'wb') as g:
    actual_date = f.readline().strip()
    while True:
        first_line = f.readline().strip()
        if not first_line: 
            break
        second_line = f.readline().strip()
        third_line = f.readline().strip()
        fourth_line = f.readline().strip()
        the_time, noun, number = first_line.split(' ')
        number = int(number)
        letter = LETTERS[number]
        new_line = '%s1:%s %s %s %s2:%s %s3:%s %s4:%s %s5:%s' % (letter, the_time, noun, number, letter, second_line, letter, third_line, letter, fourth_line, letter, actual_date)
        print (new_line)




f.close()

Answer 1

此脚本只打印输出行而不是将它们写入输出csv文件。但是，这对您来说很容易修改。另请注意，（a）最多可以用这种方式写入25行，因为只有25个字母来自＆＃39; B＆＃39;到＆＃39; Z＆＃39; （b）如果您的示例输出文件中的第一行要写入csv文件，那么它将无法输入到pandas。

该脚本的工作原理是读取第一行并将其内容保存为@Input() get arrayValue(value: string | number[]) { if (typeof value == 'string') { this._arrayValue = JSON.parse(value) } else { this._arrayValue = value } }，以便在输出行中使用。然后它一次读取四行，用于创建单个输出行。

actual_date
