How do I append the data in text files and combine multiple text files into one text file using python?

My file is like this Heading1, Heading2, Heading3, Heading4, Heading5

Alpha, Beta, Gama, Face, Human

Dog, Camel, Horse, Lion

################# Summary ###############################

Heading6 = V8CA02TB
Heading7 = 8R1
Heading8 = ENVS2F12SLB2
Heading9 = mkern2
Heading10 = 1654774930624
Heading11 =  09 13:42:10 2022

I want to make file like this

Heading1, Heading2, Heading3, Heading4, Heading5, Heading6, Heading7, Heading8, Heading9, Heading10, Heading11

Alpha, Beta, Gama, Face, Human, V8CA02TB, 8R1, ENVS2F12SLB2, mkern2, 1654774930624, 09 13:42:10 2022

Cat, Dog, Camel, Horse, Lion, V8CA02TB, 8R1, ENVS2F12SLB2, mkern2, 1654774930624, 09 13:42:10 2022

I have to do that on multiple files and then combine all the files in one text file

Any help will be appreciated.

Answer

This will parse your format.

with open('x.data') as fin:
    header = None
    rows = []
    extra = []

    for line in fin:
        if len(line) < 5:
            continue
        if not header:
            header = line.strip().split(',')
        elif 'Summary' in line:
            break
        else:
            rows.append( line.strip().split(',') )
        
    for line in fin:
        line = line.strip()
        if not line:
            continue
        left,_,right = line.partition(' = ')
        header.append( left )
        extra.append( right )

with open('out.data', 'w') as fout:
    print( ','.join(header), file=fout )
    for row in rows:
        print( ','.join(row+extra), file=fout )

Output:

A,B,C,D,E,F,G,H,I,J,K
Alpha, Beta, Gama, Face, Human,V8CA02TB,8R1,ENVS2F12SLB2,mkern2,1654774930624, 09 13:42:10 2022
Cat, Dog, Camel, Horse, Lion,V8CA02TB,8R1,ENVS2F12SLB2,mkern2,1654774930624, 09 13:42:10 2022

Combining multiple files is easy, even without Python.
