Use Walrus Operator to Find End of File in Python It is denoted by := . This operator is basically an assignment operator which is used to assign True values and then immediately print them.
Python doesn't have built-in eof detection function but that functionality is available in two ways: f. read(1) will return b'' if there are no more bytes to read. This works for text as well as binary files. The second way is to use f.
From man read:
On success, the number of bytes read is returned (zero indicates end of file), ...
