python--多维list转化为1维度list,,递归

递归实现

#多维list转化为1维度list,,递归

##递归一定要学好

def getnewList(newlist):
d = []
for element in newlist:
if not isinstance(element,list):
d.append(element)
else:
d.extend(getnewList(element))

return d

list1 =['a',[1,['c','f'],2],'b'] # 结果 ['a', 1, 'c', 'f', 2, 'b']

print(getnewList(list1))
