从列表python中删除括号

  • 772

有一张单子：

[[['Adrey'], [25], ['engineer'], ['SDI'], ['toyota']], 
[['Sasha'], [20], ['student'], ['MVI'], ['mers']]]

您需要像这里一样删除额外的括号

['Adrey', 25, 'engineer', 'SDI', 'toyota'], 
['Sasha', 20, 'student', 'MVI', 'mers']

  1. 您可以使用该模块itertools：

    from itertools import chain

arr = [
    [['Adrey'], [25], ['engineer'], ['SDI'], ['toyota']],
    [['Sasha'], [20], ['student'], ['MVI'], ['mers']]
]
new_list = [list(chain(*l)) for l in arr]
print(new_list)

    结论：

    [
    ['Adrey', 25, 'engineer', 'SDI', 'toyota'], 
    ['Sasha', 20, 'student', 'MVI', 'mers']
]
