在python的一行中动态打印字符串 [英] printing dynamically string in one line in python

问题描述

我正在尝试在一行中打印字符串.

I'm trying to print strings in one line.

我找到了解决方案，但是它们不能在Windows上正常工作.

I've found solutions but they don't works with windows correctly.

我的文本文件包含名称，我想这样打印它们

I have text file contains names and I want to print them like this

name=john，然后将john更改为下一个名字，并保留name=，我编写了此代码，但在Windows上无法正常工作:

name=john then change john to next name and keep name=, I've made this code but didn't work correctly with windows:

op = open('names.txt','r')
print 'name=',
for i in op.readlines():
    print '\r'+i.strip('\n')

感谢您的时间

推荐答案

使用senderle建议的'\ b'

Using '\b' as suggested by senderle

import sys
import time

sys.stdout.write('name=')
last_lenght = 0
with open('names.txt') as names:
    for name in names:
        sys.stdout.write('\b' * last_lenght)    # go back
        sys.stdout.write(' ' * last_lenght)     # clear last name
        sys.stdout.write('\b' * last_lenght)    # reposition
        sys.stdout.write(name.strip())
        sys.stdout.flush()
        last_lenght = len(name.strip())
        time.sleep(0.5)
