Open file for reading and writing with truncate

Question

How do I open a file for reading and writing that is also truncated to 0?

I\'ve tried:

f = open(PATH, \'w+\')

I\'m unable to read f

If you want to store the data then truncate use r+:

with open(PATH,"r+") as f:
    line = f.read()
    f.seek(0)
    f.truncate()
