删除数据框系列的数组列中带有空格（“”）的空字符串

Question

示例：

Column 1

[1, 3, " "]

[2, " ", 3]

etc.

有一个快速的列表理解功能，我可以只保留整数吗？

Answer 1

您可能正在寻找类似的东西：

a = [1, 3, " "]
b = [i for i in a if i != " "]

print(b) #> [1, 3]

如果要添加其他空格以删除：

a = [1, 3, " ", ""]
b = [i for i in a if i not in (" ", "")]

如果您只想添加int（如果有str，float等，此方法将不通用）：

a = [1, 3, " ", ""]
b = [i for i in a if isinstance(i, int)]
