Name
write_byte
Synopsis
m.write_byte(byte)
Writes byte,
which must be a single-character string, into mapping
m at the current position of
m’s file pointer,
overwriting the byte that was there, and then advances
m’s file pointer by
1. When x is a
single-character string,
m
.write_byte(
x
)
is similar to
m
.write(
x
).
However, if m’s file
pointer is at the end of m,
m
.write_byte(
x
)
silently does nothing, while
m
.write(
x
)
raises a ValueError exception. Note that this is
the reverse of the relationship between read and
read_byte at end-of-file: write
and read_byte raise ValueError,
while read and write_byte
don’t.
