Hi, I am working on the following code but am getting the error: list index out of range. I surfed through the group but somehow I am not able to fix my error.Please guide.Structure is given below: m is a list of 5 elements. I have to match elements of m from fields in file ALL_BUSES_FINAL.cvs. m=['631138', '601034', '2834', '2908', '64808']
i=0 while i<len(m): print(i) my_file = open("ALL_BUSES_FINAL.csv", "r+") for line in my_file: if m[i] in line: print (line) a.append(line) i+=1 print(a) my_file.close() The output is as follows: 0 LAKEFLD 3227,631138 ['LAKEFLD 3227,631138\n'] 1 NOBLES 3013,601034 ['LAKEFLD 3227,631138\n', 'NOBLES 3013,601034\n'] 2 GR_ISLD I,2834 ['LAKEFLD 3227,631138\n', 'NOBLES 3013,601034\n', 'GR_ISLD I,2834\n'] FTTHOMP 928,2908 ['LAKEFLD 3227,631138\n', 'NOBLES 3013,601034\n', 'GR_ISLD I,2834\n', 'FTTHOMP 928,2908\n'] VICTRYH 15,64808 ['LAKEFLD 3227,631138\n', 'NOBLES 3013,601034\n', 'GR_ISLD I,2834\n', 'FTTHOMP 928,2908\n', 'VICTRYH 15,64808\n'] Traceback (most recent call last): File "C:\Users\TJ\dist_tracking.py", line 40, in <module> if m[i] in line: IndexError: list index out of range >>> I see the line,a being correct but print (i) does not show up after 2. and index error comes up. I am too confused now. Please guide. Thanks in advance. -- http://mail.python.org/mailman/listinfo/python-list
