在执行下面的代码时,我得到了下面的错误,仅供参考
matchObj
这里返回一个元组值..
$ ./ftpParser3_re_dup.py
Traceback (most recent call last):
File "./ftpParser3_re_dup.py", line 13, in <module>
print("{0:<30}{1:<20}{2:<50}{3:<15}".format("FTP ACCOUNT","Account Type","Term Flag"))
IndexError: tuple index out of range
代码如下:
from __future__ import print_function
from signal import signal, SIGPIPE, SIG_DFL
signal(SIGPIPE,SIG_DFL)
import re
with open('all_adta', 'r') as f:
for line in f:
line = line.strip()
data = f.read()
# Making description & termflag optional in the regex pattern as it's missing in the "data_test" file with several occurrences.
regex = (r"dn:(.*?)\nftpuser: (.*)\n(?:description:* (.*))?\n(?:termflag:* (.*))")
matchObj = re.findall(regex, data)
print("{0:<30}{1:<20}{2:<50}{3:<15}".format("FTP ACCOUNT","Account Type","Term Flag"))
print("{0:<30}{1:<20}{2:<50}{3:<15}".format("-----------","------------","--------"))
for index in matchObj:
index_str = ' '.join(index)
new_str = re.sub(r'[=,]', ' ', index_str)
new_str = new_str.split()
# In below print statement we are using "index[2]" as index is tuple here, this is because
# findall() returns the matches as a list, However with groups, it returns it as a list of tuples.
print("{0:<30}{1:<20}{2:<50}{3:<15}".format(new_str[1],new_str[8],index[2],index[3]))
