本文主要是介绍Python读取txt文件查找对应内容并生成新文件,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
def modifyip(tfile, deviceAddress): # tfile为目标文件,deviceAddress为要查找的条件
desktop_path = 'C:/Users/JiajunHu/Desktop/' # 新创建的txt文件的存放路径
full_path = desktop_path + deviceAddress + '.txt' # 以deviceAddress为文件名
try:
lines = open(tfile, 'r', encoding='utf-8').readlines()
flen = len(lines) - 1
print(flen)
for i in range(flen):
if deviceAddress in lines[i]:
file = open(full_path, 'a')
file.write(lines[i - 5] + "\n" +lines[i - 4] + "\n" +
lines[i - 3]+ "\n" + lines[i] + "\n" + lines[i + 4])
except Exception as e:
print(e)
if __name__ == '__main__':
modifyip('C:/Users/JiajunHu/Desktop/log_4.txt',
'8akDIW5BSG0U') # 在'C:/Users/JiajunHu/Desktop/log_4.txt'中查找'8akDIW5BSG0U'
