Python Number Conversion Chart

Consider well the proportions of things. It is better to be
a young June bug than an old bird of paradise.

Небольшая шпаргалка для питонистов. Как переводить числа из формата в формат:
From
To
Expression
45
"45"
str(data)
45
"101101"
bin(data)
45
"2D"
hex(data)
45
"\x00\x00\x00\x2d"
struct.pack('!i', data)
"45"
45
int(data)
"45"
"3435"
data.encode('hex')
"101101"
45
int(data, 2)
"2D"
45
int(data, 16)
"2D"
"\x2d"
binascii.unhexlify(data) or data.decode('hex')
"\x00\x00\x00\x2d"
45
struct.unpack('!i', data)[0]
"\x2d"
"2D"
binascii.hexlify(data)
"3435"
"45"
data.decode('hex')

Очевидно, табличка не полная, зато общеупотребимая.
