Python如何删除小数？ [英] Python how to remove decimal?

问题描述

我找到了其他一些与此相关的主题，但无法使其正常工作。

I've found some other topics on this but I couldn't get it to work. Please pardon my naivety with Python.

Berekening1 = 8.5
Berekening2 = 8.1+4.8
Berekening3 = 8*10
Berekening4 = 3
x = Berekening1 * Berekening2 * Berekening3 + Berekening4
print "Het antwoord van de berekening is:",
round(x); print x,
print "."

我希望 x 为整数。我怎么做？我尝试了 int 和 round 。

I want x to be an integer. How do I do that? I tried both int and round.

也有人对如何删除 x 与之间的空格有所了解。在代码执行结束时结束？

Anyone also have an idea on how to remove the "space" between x and "." at the end when code is executed?

推荐答案

您需要将x重新分配为 x的值= int（x），或者，如果您只想格式化输出，也可以使用str.format：

You would need to reassign x to the value of x = int(x) or you could also use str.format if you just want the output formatted:

print "Het antwoord van de berekening is: {:.0f}.".format(x)

int和round将表现出不同的行为，如果小数点后有> = 5，则 int 将落下，但是round将四舍五入（如果您想实际使用）回合中，您可能需要将两者结合起来：

int and round will exhibit different behaviour, if you have anything >= 5 after the decimal point then int will floor but round will round up, if you want to actually use round you might want to combine the two:

In [7]: x = round(1.5)

In [8]: x
Out[8]: 2.0

In [9]: int(x)
Out[9]: 2

或再次与 str.format 组合：

In [10]: print "Het antwoord van de berekening is: {:.0f}".format(round(1.5))
Het antwoord van de berekening is: 2
