替换 Python 2.7 中的打印语句 [英] Replace printed statements in Python 2.7

问题描述

如何替换 Python 2.7 中打印的语句，例如:

 for i in range(100):打印 i,"% Completed"#Result 必须是:>>>1% 已完成

1 必须替换为 2，依此类推.但不能在不同的行或附加在同一行.

我尝试搜索它，找到了诸如

之类的解决方案

from __future__ import print_function打印(我:"+ str(i)，结束=\ r")

但它们会导致附加的打印语句.我的 print_function 是否有任何更正或有不同的解决方案?

解决方案

你想要这样的东西:

<预><代码>>>>导入系统，时间>>>对于我在范围内(100):... time.sleep(0.1)... sys.stdout.write('%d %% Completed \r' % (i,))... sys.stdout.flush()

How to replace printed statements in Python 2.7, for example:

for i in range(100):
    print i,"% Completed"

#Result Must Be:
>>> 1 % Completed 

The 1 must be replaced by 2 and so on. But not in different line or append on same line.

I tried searching about it, found solution such as

from __future__ import print_function
print("i: "+str(i),end="\r")

But they result in appended print statements. Is there any correction in my print_function or is there a different solution?

解决方案

Do you want something like this:

>>> import sys, time
>>> for i in range(100):
...     time.sleep(0.1)
...     sys.stdout.write('%d %% Completed \r' % (i,))
...     sys.stdout.flush()
