improve my python program to fetch the desire rows by using if condition
- by user2560507
unique.txt file contains: 2 columns with columns separated by tab. total.txt file contains: 3 columns each column separated by tab.
I take each row from unique.txt file and find that in total.txt file. If present then extract entire row from total.txt and save it in new output file.
###Total.txt
column a column b column c
interaction1 mitochondria_205000_225000 mitochondria_195000_215000
interaction2 mitochondria_345000_365000 mitochondria_335000_355000
interaction3 mitochondria_345000_365000 mitochondria_5000_25000
interaction4 chloroplast_115000_128207 chloroplast_35000_55000
interaction5 chloroplast_115000_128207 chloroplast_15000_35000
interaction15 2_10515000_10535000 2_10505000_10525000
###Unique.txt
column a column b
mitochondria_205000_225000 mitochondria_195000_215000
mitochondria_345000_365000 mitochondria_335000_355000
mitochondria_345000_365000 mitochondria_5000_25000
chloroplast_115000_128207 chloroplast_35000_55000
chloroplast_115000_128207 chloroplast_15000_35000
mitochondria_185000_205000 mitochondria_25000_45000
2_16595000_16615000 2_16585000_16605000
4_2785000_2805000 4_2775000_2795000
4_11395000_11415000 4_11385000_11405000
4_2875000_2895000 4_2865000_2885000
4_13745000_13765000 4_13735000_13755000
My program:
file=open('total.txt')
file2 = open('unique.txt')
all_content=file.readlines()
all_content2=file2.readlines()
store_id_lines = []
ff = open('match.dat', 'w')
for i in range(len(all_content)):
line=all_content[i].split('\t')
seq=line[1]+'\t'+line[2]
for j in range(len(all_content2)):
if all_content2[j]==seq:
ff.write(seq)
break
Problem:
but istide of giving desire output (values of those 1st column that fulfile the if condition). i nead somthing like if jth of unique.txt == ith of total.txt then write ith row of total.txt into new file.
