Read 2 files and output merged lines to 1 file

August 16, 2023

data = data2 = "";

# Reading data from file1
with open('sample1.txt') as fp:
    data = fp.read()

# Reading data from file2
with open('sample2.txt') as fp:
    data2 = fp.read()

# Merging 2 files
# To add the data of file2
# from next line


with open ('sample3.bat', 'a') as fp:
    fp.writelines("KeyHunt-Cuda -m address --coin btc --range " + data + ":" + data2 + "13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so" '\n')

Output on above code

KeyHunt-Cuda -m address --coin btc --range aaaa
bbbb
cccc:ddd
eee
fff13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so

File 1

aaaa
bbbb
cccc

File 2

ddd
eee
fff

I hoped the output would be like

KeyHunt-Cuda -m address --coin btc --range aaaa:ddd 13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so
KeyHunt-Cuda -m address --coin btc --range bbbb:eee 13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so
KeyHunt-Cuda -m address --coin btc --range cccc:fff 13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so

How should I change the code?

>Solution :

Use readlines() to read each file into a list of lines. Then loop over the lines to produce the output you want.

# Reading data from file1
with open('sample1.txt') as fp:
    data = fp.readlines()

# Reading data from file2
with open('sample2.txt') as fp:
    data2 = fp.readlines()

with open ('sample3.bat', 'a') as fp:
    for line1, line2 in zip(data, data2):
        fp.write(f"KeyHunt-Cuda -m address --coin btc --range {line1.strip()}:{line2.strip()} 13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so\n")
