any()
ascii()
bin()
bool()
bytearray()
bytes()
callable()
chr()
classmethod()
compile()
complex()
delattr()
dict()
dir()

eval()
exec()
filter()
float()
format()
frozenset()

reversed()
round()
set()
setattr()
slice()

str()
sum()
super()
tuple()
type()

所以需要先進行匯入才能使用
import math
math.floor( x )

因為pow() 函式是屬於Python的內建函式同樣屬於內建函式的還有
abs()
all()
any()
ascii()

classmethod()
compile()
complex()

而floor()函式是屬於擴充套件的math庫的所以需要先進行匯入才能使用
import math
math.floor( x )
