对包含多个表的文本文件执行计算

Question

在Python代码中，我将阅读以下文本文件：

我希望能够计算出每口井的进尺=MD out-MD in，仅当子带等于3时 我希望输出是一个表，第一列是well-001，第二列是SubZone=3的镜头 请注意，井可能多次进入分区=3，总进尺应为分区=3中所有井进尺的总和 Python编写此代码的最佳方式是什么

Answer 1

我设法得到了以下答案：

import os
import pandas as pd
import re
import io
import matplotlib.pyplot as plt
import numpy as np

plt.figure(figsize=(10,10))

df_dict = dict()
start = None
values_list = []
footage_list = []
total_footage = 0

comp_files = os.listdir('/content/sample_data/Completion/')

comp_files_list = []

for comp_file in comp_files:
  comp_files_list.append(comp_file)

if '.ipynb_checkpoints' in comp_files_list:
  comp_files_list.remove('.ipynb_checkpoints')

with open('/content/sample_data/Completion/{}'.format(comp_file),'r') as comp_well_file:
  for i, val in enumerate(comp_well_file.read().split('\n')):
    if len(val) == 0:
        continue
    if val.startswith('Well'):
        df_name = val.split(" ")[-1]
        start = i
        continue
    if val.startswith('MD'):
        values_list = []
        continue
    values = [x for x in val.split(" ") if len(x) != 0]
    values_list.append(values)
    if len(values_list) > 1:
        df_dict[df_name] = pd.DataFrame(values_list, columns=['MD in', 'MD out', 'SubZones'])
  columns=['MD in', 'MD out', 'SubZones']
  for key in df_dict.keys():
    for column in columns:
      for row in df_dict[key][column].index:
        if df_dict[key][column][row] == '3.000000':
          footage = float(df_dict[key]['MD out'][row]) - float(df_dict[key]['MD in'][row])
          total_footage =  total_footage + footage
    footage_list.append('{}, {} \n'.format(key,total_footage))
    total_footage = 0
  for i, item in enumerate(footage_list):
    print(item)
  #print(footage_list)
  #print(footage_list[0])
  #df_total_footage = pd.DataFrame(footage_list, columns = ['well_name', 'Total_Footage_in_subzone_of_interest'])
  #print(df_total_footage)

输出结果如下所示：

001井，933.7765628900015

井-002，2058.36714124
