Add test data to the code as:
file1 = '''22 110.1 33 331.5 22.7 5 271.9 17.2 33.4
4 55.1'''
Thankyou very much sir it is working......Thankyou once again for your kind
help.
only one problem I am now facing i.e. when I tried to replace test data with
filename 1.e.
file1 = open("input11.txt")
file2 = open("output22.txt")
print merge_sources([("file1", file1), ("file2", file2)])
then it is showing error
ph08...@linux-af0n:~> python new.py
Traceback (most recent call last):
File "new.py", line 25, in
print merge_sources([("file1", file1), ("file2", file2)])
File "new.py", line 9, in merge_sources
for line in sce.split(os.linesep):
AttributeError: 'file' object has no attribute 'split'
ph08...@linux-af0n:~>
where my input11.txt is:
'''187 7.79 122.27 54.37 4.26 179.75
194 8.00 121.23 54.79 4.12 180.06
15 8.45 119.04 55.02 4.08 178.89
176 7.78 118.68 54.57 4.20 181.06
180 7.50 119.21 53.93 179.80
190 7.58 120.44 54.62 4.25 180.02
152 8.39 120.63 55.10 4.15 179.10
154 7.79 119.62 54.47 4.22 180.46
175 8.42 120.50 55.31 4.04 180.33'''
and output22.txt is:
'''15 H
37 H
95 T
124 H
130 H
152 H
154 H
158 H
164 H
175 H
176 H
180 H
187 H
190 T
194 C'''
since my files are very big hence i want to give filename as input.
