Python：用print命令避免新行[duplicate](Python: avoid new line with print command [duplicate])

Python：用print命令避免新行[duplicate](Python: avoid new line with print command [duplicate])

这个问题已经在这里有一个答案：

如何打印没有换行符或空格？ 26答案

我今天开始编程，并在Python中遇到这个问题。 这很笨，但我不知道该怎么做。 当我使用打印命令时，它会打印任何我想要的，然后转到另一行。 例如：

print "this should be"; print "on the same line"

应该返回：

这应该在同一行

而是返回：

这应该是 在同一行

更准确地说，我正在尝试创建一个程序， if告诉我一个数字是否为2

def test2(x): if x == 2: print "Yeah bro, that's tottaly a two" else: print "Nope, that is not a two. That is a (x)"

但是它不会将最后一个(x)识别为输入的值，而是正确打印：“（x）”（带括号的字母）。 为了使其工作，我必须写：

print "Nope, that is not a two. That is a"; print (x)

如果我输入test2(3) ，它给出：

不，不是两个，就是一个 3

所以我需要使Python在打印行内识别我的（x）号码; 或打印两个单独的东西，但在同一行。 先谢谢，对不起这样一个愚蠢的问题。

重要提示 ：我使用的是2.5.4版本

另一个注意事项：如果我print "Thing" , print "Thing2"它在第二个打印中显示“Syntax error”。

How to print without newline or space? 21 answers

I've started programming today and have this issue with Python. It's pretty dumb but I can't figure out how to do it. When I use the print command, it prints whatever I want and then goes to a different line. For example:

print "this should be"; print "on the same line"

Should return:

this should be on the same line

but instead returns:

this should be on the same line

More precisely I was trying to create a program with if that told me whether a number was a 2 or not

def test2(x): if x == 2: print "Yeah bro, that's tottaly a two" else: print "Nope, that is not a two. That is a (x)"

But it doesn't recognise the last (x) as the value entered, and rather prints exactly: "(x)" (the letter with the brackets). To make it work I have to write:

print "Nope, that is not a two. That is a"; print (x)

And if e.g. I enter test2(3) that gives:

Nope, that is not a two, that is a 3

So either i need to make Python recognise my (x) inside a print line as the number; or to print two separate things but on the same line. Thanks in advance and sorry for such a stupid question.

IMPORTANT NOTE: I am using version 2.5.4

Another note: If i put print "Thing" , print "Thing2" it says "Syntax error" on the 2nd print.

您可以使用后缀逗号来避免打印换行符：

print "this should be", print "on the same line"

你不需要这样来简单地打印一个变量：

print "Nope, that is not a two. That is a", x

注意：从Python 3.x及以上版本

print("Nope, that is not a two. That is a", x)

In Python 3.x, you can use the end argument to the print() function to prevent a newline character from being printed:

print("Nope, that is not a two. That is a", end="")

In Python 2.x, you can use a trailing comma:

print "this should be", print "on the same line"

You don't need this to simply print a variable, though:

print "Nope, that is not a two. That is a", x

Note that the trailing comma still results in a space being printed at the end of the line, i.e. it's equivalent to using end=" " in Python 3. To suppress the space character as well, you can either use

from __future__ import print_function

to get access to the Python 3 print function or use sys.stdout.write().
