如何将字符串插入到具有相同多次出现的另一个字符串中

Question

如何简化以下语法？

three='Three'
result='One-Two-%s, One-Two-%s, One-Two-%s'%(three,three,three))

稍后编辑：

另一个惊喜：获得KeyError: 'border'：

color='#262626'
style="QProgressBar{background-color: {ph:s}}".format(ph=color)

Answer 1

>>> three = 'Three'
>>> result = 'One-Two-{ph:s}, One-Two-{ph:s}, One-Two-{ph:s}'.format(ph=three)
>>> print result
One-Two-Three, One-Two-Three, One-Two-Three

修改：

>>> style="QProgressBar{{background-color: {ph:s}}}".format(ph=color)
>>> print style
QProgressBar{background-color: #262626}

Answer 2

尝试new-style formatting。

您也可以使用字典扩展来执行多个变量。

three='Three'
result='One-Two-{x:}, One-Two-{x:}, One-Two-{x:}'.format(**{'x': three})

Answer 3

您可以使用string formatting.在您的示例中，您可以执行此操作：

three = "Three"
result = "One-Two-{0}, One-Two-{0}, One-Two-{0}".format(three)

对于另一个问题，请将其更改为：

style="QProgressBar{{background-color: {0}}}".format(color)
