Python: How to move N lines from one file to another

Question

I am trying something like this, but in Python and not PowerShell: https://askubuntu.com/questions/1105376/how-to-move-n-lines-from-one-file-to-another

Can somebody help me? I need to move (cut, not only copy) the first 100 lines from a text file to another empty/new text file.

Thanks in advance

Answer 1

x = 100
with open("C:/path/to/file/you/want/to/copy/from",'r') as f1:
    data = f1.readlines()
with open("C:/path/to/file/you/want/to/copy/from",'w') as f1:
    for line in data[x:]:
        f1.write(line)
with open("C:/path/to/file/you/want/to/copy/to",'w') as f2:
    for line in data[:x]:
        f2.write(line)
