我觉得可以通过列表理解和基于相关答案的功能来改善此代码段。然后,我继续更改此代码段:
file.url
无法使用的新版本:
l=[['rfn'], ['abod'], [['splash', 'aesthet', 'art']], [['splash', 'aesthet', 'anim']], ['fabl'], ['clean']]
flat_list = []
for sublist in l:
print("sublist: ", sublist)
for item in sublist:
if type(item)== list:
for i in item:
flat_list.append(i)
else:
flat_list.append(item)
print(flat_list)
哪些人由于语法错误而抱怨:
文件“”,第33行
l=[['rfn'], ['abod'], [['splash', 'aesthet', 'art']], [['splash', 'aesthet', 'anim']], ['fabl'], ['clean']]
def foo(item):
flat_l=[]
if type(item)== list:
for i in item:
flat_l.append(i)
else:
flat_l.append(item)
return flat_l
flat_list=[item for sublist in l foo(item) for item in sublist]
print(flat_list)
^
SyntaxError:语法无效
答案 0 :(得分:0)
我在python3中的代码
l=[['rfn'], ['abod'], [['splash', 'aesthet', 'art']], [['splash', 'aesthet', 'anim']], ['fabl'], ['clean']]
e=[]
any(e.extend(i[0]) if isinstance(i[0], list) else e.extend(i) for i in l)
print(e)
