[英]Validating saved text file with Python to check if parameters are set
I've got a problem with validating text file.我在验证文本文件时遇到问题。 I need to check if parameters that I set are correctly saved.
我需要检查我设置的参数是否正确保存。 File name is an actual date and time and I need to check if parameters that were send are in this text (log) file.
文件名是实际日期和时间,我需要检查发送的参数是否在此文本(日志)文件中。 Below you can find my code:
您可以在下面找到我的代码:
Arguments are sent with argpars eg. Arguments 与 argpars 一起发送,例如。 parser.add_argument("freq", type=int)
parser.add_argument(“频率”,类型=int)
print('Saving Measurement...')
print(inst.write(':MMEMory:STORe:TRACe 0, "%s"' % timestr)) #Saving file on the inst
time.sleep(1) #Wait for file to save
print('Downloading file from device...')
ftp = FTP('XX.XX.XXX.XXX')
ftp.login()
ftp.retrbinary('RETR %s'% timestr + '.spa', open(timestr + '.spa', 'wb').write) #downloading saved file into a directory where you run script
print('Done, saved as: ' + timestr)
time.sleep(1)
with open (timestr + '.spa') as f:
if (str(args.freq)) in f.read():
print("saved correctly")
ftp.delete(timestr + '.spa') #Delete file from inst
ftp.quit()
I'm not sure if it works for me.我不确定它是否适合我。 Thank you for your help
谢谢您的帮助
You could use the re module
to help you find a date pattern inside your file.您可以使用
re module
来帮助您在文件中找到日期模式。 I will give you a little example code that searches, at least for this case, this date pattern dd-mm-yyyy我会给你一个小的示例代码,至少在这种情况下,搜索这个日期模式 dd-mm-yyyy
import re
filepath = 'your-file-path.spa'
regex = '\d\d-\d\d-\d\d\d\d'
with open(filepath, 'r') as f:
file = f.read()
dates_found = re.findall(regex, file)
# dates_found will be an array with all the dates found in the file
print(dates_found)
You could use any regex you want as the first argument of re.findall(regex, file)
您可以使用任何您想要的正则表达式作为
re.findall(regex, file)
的第一个参数
