def number_to_bits(number):

if number:

bits = []

while number:

number, remainder = divmod(number, 2)

bits.insert(0, remainder)

return bits

else:

return [0]

number_to_bits(6)

characteristics

stderr, you can output the selection to the specified file:

@pysnooper.snoop( /my/log/file.log )

View the variable values of some non-local variables:

@pysnooper.snoop(variables=( foo.bar , self.whatever ))

Snoop lines showing functions called by functions:

@pysnooper.snoop(depth=2)
