Question

我已经能够像下面这样使用python制作一个平面列表来拆开元组列表：

{
    "username": "bob murrey",
    "id": 200
}

输出：

items = [('Brandon', 'WME', 'phone'), ('Brian', 'Endeavor', 'phone one'), ('Duncan', 'Entertainment', 'phone two')]
flat_list =  [i for elem in items for i in elem]
print(flat_list)

如果我使用像['Brandon', 'WME', 'phone', 'Brian', 'Endeavor', 'phone one', 'Duncan', 'Entertainment', 'phone two']这样的星号，列表将变为：

print(*flat_list)

如何使列表如下所示？

Brandon WME phone Brian Endeavor phone one Duncan Entertainment phone two

Answer 1

使用string.join。示例：

print(", ".join(["a", "b", "c"]))

Answer 2

您要使用定界符https://github.com/gearman/gearmand/issues/63字符串：

>>> ", ".join(flat_list)
'Brandon, WME, phone, Brian, Endeavor, phone one, Duncan, Entertainment, phone two'

Answer 3

只需更改print的sep参数：

items = [('Brandon', 'WME', 'phone'), ('Brian', 'Endeavor', 'phone one'), ('Duncan', 'Entertainment', 'phone two')]
flat_list = [i for elem in items for i in elem]
print(*flat_list, sep=", ")

输出

Brandon, WME, phone, Brian, Endeavor, phone one, Duncan, Entertainment, phone two

Answer 4

您可能不确定使用np.flatten（）。

无法以自定义方式解压缩平面清单
