Someone in the QQ group, it is very simple, written out to play:
Text file X.txt content is
122 222 861333200056610 8613032222202103335 861303433232810005 86130113188001000 861313254618610000 8613312073654100000 8613034348185100001 8613194682965100003 8613102251300100006 8613032226257100005 8613116000937
Two numbers have a '/ t'
f = Open ('x.txt') # If your x.txt file is not in Python's path, you must use absolute path L1 = f.readLines () # This time the result of L1 is a list, each element is Each line of the file, including the stroke symbol '/n'l1=[x.split('/t') for x in l1] L1 = [[x [0], x [1] .REPLACE ('/ n', '')] for x in l1] # 这里 这里 每 的 '/ n' symbol f.close () # Close the file just opened # now L1 is a List: It is also a list The two elements of the latter store the first and second column numbers f = ('y.txt', 'W') # of the file, respectively, to store the result of the result
# At this time, I don't know why I always have an error directly. That 10005 is always ranked to the third position of the countdown. It is really strange.
L2 = [[INT (x [0]), int (x [1])] for x in l1] l2.sort () L2 = [STR (x [0]) '/ t' STR (x [ 1]) '/ n' for x in l2] f.writeLines [l2] f.close ()
The result of final Y.TXT is:
1,086,130,322,222,021,000 861313254618610000 861331207365410005 8613194682965100000 8613034348185100001 8613034332328100003 8613102251300100005 8613116000937100006 8613032226257103335 8613011318800122222 8613332000566
The result is sorted according to the numbers of the first column.
Note: If L1.Sort () is directly paired, the result is:
1,086,130,322,222,021,000 861313254618610000 8613312073654100000 8613034348185100001 8613034332328100003 8613102251300100005 8613116000937100006 8613194682965103335 8613011318800122222 861303222625710005 very strange 8613332000566
If it is in the command line, the specific steps are as follows:
