问题描述
我是 python 新手,并试图使用我的代码来理解具有文本的 csv 文件的模式/上下文。我的代码能够一次为一个文件执行此操作。我希望它遍历目录中的多个 csv 文件并获取上下文
import pandas as pd
def search_multiple_strings_in_file(file_name,list_of_strings):
"""Get line from the file along with line numbers,which contains any string from the list"""
line_number = 0
list_of_results = []
# Open the file in read only mode
with open("Sandrasales.csv",'r') as read_obj:
# Read all lines in the file one by one
for line in read_obj:
line_number += 1
# For each line,check if line contains any string from the list of strings
for string_to_search in list_of_strings:
if string_to_search in line:
# If any string is found in line,then append that line along with line number in list
list_of_results.append((string_to_search,line_number,line.rstrip()))
# Return list of tuples containing matched string,line numbers and lines where string is found
return list_of_results
# search for given strings in the file 'sample.txt'
matched_lines = search_multiple_strings_in_file('SandraSales.csv',['renewal','provision','annual limit'])
print('Total Matched lines : ',len(matched_lines))
for elem in matched_lines:
print('Word = ',elem[0],' :: Line Number = ',elem[1],' :: Line = ',elem[2])
假设我的文件夹/目录是 C:\Users\jj\Desktop\analysis,其中所有的 csv 文件都在那里。
