将多行返回到列表中

Question

我有结果：

Alice
Washington Street
Doctor
Wong Li
Lincoln Street
Teacher
Suresh
Hamilton Street
Engineer

我可以通过以下方式将其转换为列表：

>>>result_list = [y for y in (x.strip() for x in result.splitlines()) if y] #which i found it in SO
>>>result_list
['Alice', 'Washington Street', 'Doctor', 'Wong Li', 'Lincoln Street', 'Teacher', 'Suresh', 'Hamilton Street', 'Engineer']

但我需要的是

[['Alice', 'Washington Street', 'Doctor'], ['Wong Li', 'Lincoln Street', 'Teacher'], ['Suresh', 'Hamilton Street', 'Engineer']]

...基本上按每3行分组

之后我将使用熊猫将其列为三列名称，地址和职业。

Answer 1

使用具有适当start, stop, step值的范围的适当值构建所需切片的列表：

result_list = [result_list[i:i+3] for i in range(0, len(result_list), 3)]
# [['Alice', 'Washington Street', 'Doctor'], ['Wong Li', 'Lincoln Street', 'Teacher'], ['Suresh', 'Hamilton Street', 'Engineer']]

Answer 2

你可以像你一样制作列表result_list，然后使用列表理解和适当的切片..

result_list = [y for y in (x.strip() for x in result.splitlines()) if y]

result_list = [result_list[i:i+3] for i in range(0, len(result_list), 3)]

# output : [['Alice', 'Washington Street', 'Doctor'], ['Wong Li', 'Lincoln Street', 'Teacher'], ['Suresh', 'Hamilton Street', 'Engineer']]
