如何分隔.txt文件的列。将所有列合并为一个脚本？

Question

我有一个如下所示的文本文件：

      UWI/API             WELLNAME             WELLNO              LABEL                OPER               PRODFM         SURFLAT     SURFLON      BOTLAT      BOTLON   PERFTOP PERFBASE     PERFSOURCE         WELL        WELL        WELL        WELL        WELL        WELL        WELL      SYM

当我运行这段代码时，输出将所有第一行放入一列。我希望第一列是“UWI/API”，第二列是“WELLNAME”，等等。。。如您所见，数据不是用逗号分隔的，而是用空格分隔的。数据有点混乱？它没有对齐。标题应为“UWI/API”至“INJWTR”

这是我的密码：

import pandas as pd

df = pd.read_csv(r'C:/Users/mmcintyre/Documents/Teresa CO2 Injectors_Spaces.txt',sep=r'\s{2,}')

df.to_csv(r'C:/Users/mmcintyre/Documents/Teresa.csv',index=None)

输出是这样的：https://sru365edu-my.sharepoint.com/:x:/g/personal/mam1064_sru_edu/Ebq0tpHveAJBu710UcDt82IB23gmRs6nNrTE-MtDUgkU6Q？e=byhjuL

我突出显示了位置不正确的行。我不确定这是否可以解决

谢谢！ 摩根

这些数据似乎很难解析。我用一堆csv解析器尝试了许多设置，但我认为没有一种干净的方法来解析如此混乱的数据。我选择了肮脏的方法。如果你只需要为这个文件，以下应该工作，如果你需要经常这样做，我不保证这将永远工作干净

#! /usr/bin/env python

import csv

data = []

with open('Teresa CO2 Injectors_Spaces.TXT') as file_handler:

    header = file_handler.readline().strip().split()
    header2 = ['' for i in range(13)] + file_handler.readline().strip().split() + ['']

    data.append(header)
    data.append(header2)

    for row in file_handler.readlines():

        tempRow = []

        UWIAPI = row[0:20]
        WELLNAME = row[20:40]
        WELLNO = row[40:60]
        LABEL = row[60:80]
        OPER = row[80:100]
        PRODFM = row[100:120]
        SURFLAT = row[120:132]
        SURFLON = row[132:144]
        BOTLAT = row[144:156]
        BOTLON = row[156:168]
        PERFTOP = row[168:176]
        PERFBASE = row[176:184]
        PERFSOURCE = row[184:200]
        ELEV_KB = row[200:220]
        TD = row[218:228]
        COMP_DATE = row[228:240]
        SPUD_DATE = row[240:252]
        INJLIQ = row[252:264]
        INJGAS = row[264:276]
        INJWTR = row[276::]
        SYM = ''

        tempRow = [
            UWIAPI.strip(),
            WELLNAME.strip(),
            WELLNO.strip(),
            LABEL.strip(),
            OPER.strip(),
            PRODFM.strip(),
            SURFLAT.strip(),
            SURFLON.strip(),
            BOTLAT.strip(),
            BOTLON.strip(),
            PERFTOP.strip(),
            PERFBASE.strip(),
            PERFSOURCE.strip(),
            ELEV_KB.strip(),
            TD.strip(),
            COMP_DATE.strip(),
            SPUD_DATE.strip(),
            INJLIQ.strip(),
            INJGAS.strip(),
            INJWTR.strip(),
            SYM,
        ]

        data.append(tempRow)

with open('example.csv', 'w+') as fh:

    writer = csv.writer(fh, delimiter=',')

    for row in data:

        writer.writerow(row)
