我试过itertools,map()但我不知道错了什么。我有这个:
[['>Fungi|A0A017STG4.1/69-603 UP-domain-containing protein {ECO:0000313|EMBL:EYE99555.1}', ['-', '-', '-', ... , '-', '-', '-', '-']],['>Fungi|A0A017STG4.1/69-603 UP1-domain-containing protein {ECO:0000313|EMBL:EYE99555.1}', ['-', '-', '-', ... , '-', '-', '-', '-']],['>Fungi|A0A017STG4.1/69-603 UP12-domain-containing protein {ECO:0000313|EMBL:EYE99555.1}', ['-', '-', '-', ... , '-', '-', '-', '-']]]
我想要这个:
[['>Fungi|A0A017STG4.1/69-603 UP-domain-containing protein {ECO:0000313|EMBL:EYE99555.1}','-', '-', '-', ... , '-', '-', '-', '-'],['>Fungi|A0A017STG4.1/69-603 UP1-domain-containing protein {ECO:0000313|EMBL:EYE99555.1}','-', '-', '-', ... , '-', '-', '-', '-'],['>Fungi|A0A017STG4.1/69-603 UP10-domain-containing protein {ECO:0000313|EMBL:EYE99555.1}','-', '-', '-', ... , '-', '-', '-', '-']]
我试过
for i in x:
map(i,[])
和这个
import itertools
a = [["a","b"], ["c"]]
print list(itertools.chain.from_iterable(a))
请开导我!

必须有更好的 Pythonic 解决方案,但您可以使用:
n = []
for x in your_list:
temp_list = [x[0]]
[temp_list.append(y) for y in x[1]]
n.append(temp_list)
print(n)
输出:
[['>Fungi|A0A017STG4.1/69-603 UP-domain-containing protein {ECO:0000313|EMBL:EYE99555.1}', '-', '-', '-', Ellipsis, '-', '-', '-', '-'], ['>Fungi|A0A017STG4.1/69-603 UP1-domain-containing protein {ECO:0000313|EMBL:EYE99555.1}', '-', '-', '-', Ellipsis, '-', '-', '-', '-'], ['>Fungi|A0A017STG4.1/69-603 UP12-domain-containing protein {ECO:0000313|EMBL:EYE99555.1}', '-', '-', '-', Ellipsis, '-', '-', '-', '-']]

简单的oneliner可以做到:
[sum(x, []) for x in yourlist]
注意sum(x,[])相当慢,因此对于严重的列表合并使用更多有趣和点亮的快速列表合并技术
例如,简单的两个衬垫更快import itertools
map(list, (map(itertools.chain.from_iterable, yourlist)))
