[英]Printing no output to a text file in python while reading specific lines
[英]While reading text file some lines are not detected?
text_file.txt
我得到的是第一個打印語句的輸出,而不是第二個打印語句的輸出。請向我提供正確的代碼,我需要編碼或解碼嗎? 請幫我即時了解python3
這是您要實現的目標的更直接的實現。 您可以將文件讀入Python列表,並通過Python列表索引引用每一行
with open('text_file.txt','r') as f: # automatically closes the file
input_file = f.readlines() # Read all lines into a Python list
for line_num in range(len(input_file)):
if "INBOIS BERCUKAI" in input_file[line_num]:
print(input_file[line_num + 2]) # offset by any number you want
# same for other if statements
