[Python] Conversion between int and bit

	"""int to bit (string)"""
	#a method of converting int into bit
	>>> bit = bin(43261596)
	>>> bit
	'0b10100101000001111010011100' #bit is a string
	# another method of converting int into bit
	# '{0:0ab}'.format(n)
	# the first 0 means taking the variable at argument position 0
	# the second 0 means zero-padded on the left
	# a: the total number of bits
	# b: means binary
	# n: the int number;
	>>> bitStr = '{0:032b}'.format(43261596)
	>>> bitStr
	'00000010100101000001111010011100' #bitStr is a string with 0 peddled on the left, total 32 bits
	"""bit into int"""
	>>> int('00000010100101000001111010011100', 2)
