Swap Value for many attribute

How can i swap the value for all attribute?? I want FieldIP = 1. MomentIP=1 FieldOP =3 and so on.

Table of example

FieldIP =3                  FieldOP    =1        
MomentIP =3                 MomentOP   =1  
NormalizeMomentIP =3        NormalizeMomentOP  =1       
ixfwdIP  =3                 ixfwdOP       =1
iyfwdIP  =3                 iyfwdOP       =1
ixbwdIP  =3                 ixbwdOP       =1
iybwdIP  =3                 iybwdOP       =1
MsAvgIP  =3                 MsAvgOP       =1
MsStdIP  =3                 MsStdOP       =1
HkIP     =3                 HkOP          =1
NegFieldIP  =3              NegFieldOP    =1
NegNormalizeMomentIP =3     NegNormalizeMomentOP  =1     
NegFieldBotIP =3            NegFieldBotOPx`       =1
NegNormalizeMomentBotIP =3  NegNormalizeMomentBotOP   =1

How can i swap the value for all attribute?? Is there any shorter way? This is the code i did. If i did finish all 14 attribute it will be very long as i have to declare 28 variable...

    x = FieldIP
    y = FieldOP
    ...
    if ( HkOP > HkIP):
        FieldOP = x
        FieldIP = y
        print "Swapped"

Result i want

FieldIP =1                  FieldOP    =3       
MomentIP =1                 MomentOP   =3  
NormalizeMomentIP =1        NormalizeMomentOP  =3       
ixfwdIP  =1                 ixfwdOP       =3
iyfwdIP  =1                 iyfwdOP       =3
ixbwdIP  =1                 ixbwdOP       =3
iybwdIP  =1                 iybwdOP       =3
MsAvgIP  =1                 MsAvgOP       =3
MsStdIP  =1                 MsStdOP       =3
HkIP     =1                 HkOP          =3
NegFieldIP  =1              NegFieldOP    =3
NegNormalizeMomentIP =1     NegNormalizeMomentOP  =3     
NegFieldBotIP =1            NegFieldBotOPx`       =3
NegNormalizeMomentBotIP =1  NegNormalizeMomentBotOP   =3

I'm assuming this data of yours is in a text file of some sort.

Try something like this:

import re
# read your data
lines = open('mytable.txt').readlines()
# regex to capture your 'values'
regex = re.compile(r'(.*?=)([0-9]+)(.*?=)([0-9]+)')
for line in lines:
    # for each line, match the value groups and substitute swapped values
    print regex.sub(r'\1\4\3\2', line)

Should print the table with swapped values, and preserve the whitespace too.

You can iterate through local vars to do so:

key = key2 = None
for key in locals():
    if key.endswith('OP'):
        key2 = key[:-2] + 'IP'
        if locals()[key] > locals()[key2]:
            locals()[key], locals()[key2] = locals()[key2], locals()[key]
            print 'swapped'

You have to declare key and key2 before the for loop, not inside it.
