Python script - control flow statements
Hi guys.I'm just beginner of python.
 I'm just trying to do some analysis on simple input file.
it has 6 columns and i want to consider k,l and m,n if i and j are +
after that checking which value is greater or lower in k,l and m,n
I have included logic header just to explain what I was trying to do
plz take a look at my python script.Plz Suggest me any ideas

Inputfile:

columns k,l,i,m,n,j
30,50,+,100,200,+
210,250,+,100,200,+
150,180,+,100,200,+
80,150,+,100,200,+
150,250,+,100,200,+
100,200,-,100,200,-
200,100,+,200,100,-
100,250,-,50,60,-

logic:

while i and j columns are +,+

if k<m and l<m (30<100 and 50<100)
print all the columns plus "good"
elif k>n and l>n (210>100 and 250>200)
print all the columns with "good"
elif k>m and l<n
print all... with "bad"
elif k>m and l>n
print all.....with "average"
elif k<m and l<n
print all......with "avergae"

outputfile:

columns k,l,i,m,n,j
30,50,+,100,200,+,good
210,250,+,100,200,+,good
150,180,+,100,200,+,bad
80,150,+,100,200,+,average
150,250,+,100,200,+,averge

Python script_raw

Quote:
d = {}

for line in open ("filename"): #open file
line = line.strip().split() #splitting file into columns
d.setdefault (line[-1],[-3],[])
d[-1][-3].append(line[0][1][3][4])

for i,j,k,l,m,n in d.iteritems ():


while i = +, j = +:

if (k<m, l<m):
print k, '\t', l, '\t', i, '\t', m, '\t', n,'\t', j, '\t', 'Good'

elif (k>n, l>n):
print k, '\t', l, '\t', i, '\t', m, '\t', n,'\t', j, '\t', 'Good'

elif (k>m, l<n):
print k, '\t', l, '\t', i, '\t', m, '\t', n,'\t', j, '\t', 'Bad'

elif (k<m, l<n):
print k, '\t', l, '\t', i, '\t', m, '\t', n,'\t', j, '\t', 'Average'

elif (k>m, l>n):
print k, '\t', l, '\t', i, '\t', m, '\t', n,'\t', j, '\t', 'Average'

break

put your Python code in code tags, not quote tags.
Code:
for line in open("file"):
    oline=line.strip()
    if j =="+" and i=="+":
        k,l,i,m,n,j=oline.split(",")
        if k<m and  l<m:
            print oline,",good"
        elif .....

if you are a beginner, you should go read the documentation. Read the tutorial and get familiarize with Python. From the way you write the code, i believe you haven't even look at the basics. (there is no need for open and close brackets in Python, except for functions/tuples)

NameError: name 'j' is not defined
Press any key to continue . . .

Code:

            print oline,",Good"
        elif k>n and l>n:
            print oline,",Good"
        elif k>m and l<n:
            print oline,",IBad"
        elif k<m and l<n:
            print oline,",Avg"
        elif k>m and l>n:
            print oline,",Avg"

please look at the error carefully, its says "j" is not defined. that's all there is. very straightforward.
Code:
    if j=="+" and i=="+":
        k,l,i,m,n,j=oline.split(",")

the above is the offending error. I leave it to you to try finding it yourself. the split should be done before the checking for j value. simple? pls read the tutorial before posting another query.
