我试图将math.floor函数应用于使用str()
函数的一些变量......这样做的正确方法是什么?
这是我的代码:
import math
x = str(10.3)
y = str(22)
z = str(2020)
print "x equals " + x
print "y equals " + y
print "z equals " + z
#playing around with the math module here. The confusion begins...
#how do I turn my str() functions back into integers and apply the floor function of the math module?
xfloor = math.floor(x)
zsqrt = math.sqrt(z)
print "When we print the variable \"xfloor\" it rounds " + x + "down into " + xfloor + "."
print "When we print the variable \"zsqrt\" it finds the sqareroot of " + z + "which is " + zsqrt + "."
raw_input("Press the enter key to continue.")
欢迎任何和所有的帮助。

把它们扔掉:
xfloor = math.floor(float(x))
zsqrt = math.sqrt(float(z))
但这不是推荐的做法,因为您不必要地将其转换为str
。要print
使用str.format
print "x equals {}".format(x)
为此,您无需转发str
。
