read(size=-1)

[7stud]

Suppose I write:

f = open("myimg.jpg")
f.read(10)
According to the docs,
-----------
read([size])

Read at most size bytes from the file....The bytes are returned as a
string object.
----------

How does python convert a byte to a string?

Each byte of the file occupies one character in the string. As you could
have found out (more quickly than posting!) by actually typing your
example into an interpreter.

>>f = open('desktop01-real.jpg')
f.read(10)

'\xff\xd8\xff\xe0\x00\x10JFIF'

>>>

A string _is_ a sequence of bytes - there is nothing to convert.
