Writing String to Binary file
• To store string in binary file, we must convert it to binary
format either by prefixing the string with ‘b’ or using the
encode() function.
• For e.g.
VINOD KUMAR VERMA,PGT(CS), KV OEF KANPUR &
SACHIN BHARDWAJ, PGT(CS), KV NO.1 TEZPUR
We can use ‘a’ in
place of ‘w’ for
append
