how to add a content in between a text using append
any one know pls share code.

Answer 1

you could just read the file, use string manipulation(list manipulation or whatever for bytes) and overwrite the contend with your data.
or if you have big files:
go to point using seek()
read the file from wherever you want to insert, use string manipulation(or whatever) and write from point you want to insert to end.(so use seek() again and r+ mode) see this link: https://ubuntuforums.org/showthread.php?t=1847959

Answer 2

with open("test.txt", "a") as myfile:
myfile.write("appended text")
