Why is hexdump showing 0a at the beginning of my python output?

This is in my code:

if p1 == "something":
   f = open("output.txt", "a")
   f.write("Helloworld")
   f.close()

And the hexdump shows this:

Expected output:

00000000: 48 65 6c 6c 6f 77 6f 72  Hellowor     
00000008: 6c 64                    ld

Current output

00000000: 0a 48 65 6c 6c 6f 77 6f  .Hellowo   
00000008: 72 6c 64                 rld

PS: I have tried strip, lstrip, removing first character...

I can't reproduce this.

Make sure you didn't create the file before, some text editors like to append a newline (0x0a) on save.

Use f = open("output.txt", "w") to overwrite existing content in the file.

You're opening your file in append mode. Open your file in write mode, using 'w' instead of 'a', or check whether you did not append anything to the file beforehand, as Turun Ambartanen said.
