在Python的同一行上有多个打印 [英] multiple prints on the same line in Python

问题描述

我想运行一个脚本，该脚本基本上显示如下输出:

I want to run a script, which basically shows an output like this:

Installing XXX...               [DONE]

当前，我先打印Installing XXX...，然后再打印[DONE].

Currently, I print Installing XXX... first and then I print [DONE].

但是，我现在想在同一行上打印Installing xxx...和[DONE].

However, I now want to print Installing xxx... and [DONE] on the same line.

有什么想法吗?

推荐答案

您可以使用print语句执行此操作，而无需导入sys.

You can use the print statement to do this without importing sys.

def install_xxx():
   print "Installing XXX...      ",

install_xxx()
print "[DONE]"

print行末尾的逗号阻止print发出新行(您应注意，输出末尾会有多余的空格).

The comma on the end of the print line prevents print from issuing a new line (you should note that there will be an extra space at the end of the output).

Python 3解决方案
由于以上内容在Python 3中不起作用，因此您可以改为这样做(同样，无需导入sys):

The Python 3 Solution
Since the above does not work in Python 3, you can do this instead (again, without importing sys):

def install_xxx():
    print("Installing XXX...      ", end="", flush=True)

install_xxx()
print("[DONE]")

打印功能接受默认值为"\n"的end参数.将其设置为空字符串可防止其在行尾发布新行.

The print function accepts an end parameter which defaults to "\n". Setting it to an empty string prevents it from issuing a new line at the end of the line.
