％数组中的元组？ python（不将元组附加到数组中）

时间：2018-08-07 03:23:48

标签： python

假设您有以下内容：

x=10
l=11
list = ["%s bla","%s bla"%(x,l)]
print(list)

在这种情况下，您会收到以下错误消息：

  

TypeError：在字符串格式化期间并非所有参数都已转换

我假设这是由于元组位于数组中。 使用.format，您将获得：

['{} bla', '11 bla']

我的问题有解决方案吗？

您需要为每个字符串赋予自己的变量：

答案 1 :(得分：1)

使用zip和列表推导来组合值。

>>> x = 10
>>> L = 11
>>> lst = ["%s bla","%s bla"]
>>> [s % n for s, n in zip(lst, (x, L))]
['10 bla', '11 bla']

在您的示例中，您仅将格式应用于第二个字符串，该字符串仅具有一个格式说明符，但是您向其传递了两个值，因此会出现错误。

如果您想使用str.format，只需这样做。

>>> lst2 = ["{} bla","{} bla"]
>>> [s.format(n) for s, n in zip(lst2, (x, L))]
['10 bla', '11 bla']

答案 2 :(得分：0)

在最新版本的python（3.6或更高版本）中，您还可以执行以下操作：

x=10
l=11
l2 = [f"{x} bla",f"{l} bla"]
print(l2)

输出：

['10 bla', '11 bla']

答案 3 :(得分：0)

这是因为您仅将其分配给最后一个元素的另一个选项是：

>>> x=10
>>> y=11
>>> l = ["%s bla","%s bla"]
>>> list(map(lambda x: x[0]%x[1],zip(l,[x,y])))
['10 bla', '11 bla']
