You could try using the os library in python.

import os

# retrieve current files in the directory
fnames = os.listdir()
# split the string by '_' and access the middle index
new_names = [fnames.split('_')[1]+'.txt' for fname in fnames]

for oldname, newname in zip(fnames, new_names):
    os.rename(oldname, newname)

This will do the work for the current directory.

import os

fnames = os.listdir()
for oldName in fnames:
    if oldName[-4:] == '.txt' and len(oldName) - len(oldName.replace("_","")) == 2:
        s = oldName.split('_')
        os.rename(oldName, s[1]+'_'+s[2]+'.txt')
