在python中用split以逗号分隔若中间有空的项自动设为0 这个该怎么实现呢？求解答，谢谢！ Python中输入的文件本来就有空格,为什么还要用split...

str_new=str.replace(' ','0')
str_new.split(",")
最后输出：['I0love0Pekin', '0and0you0?']
如果还想分开:
str_new_new=str_new.split(",")
str_new_new[0].split('0')+str_new_new[1].split('0')
最后输出：['I', 'love', 'Pekin', '', 'and', 'you', '?']
a = '1,2,,,4,,5'
[x if x else '0' for x in a.split(',')]
public class Fruit{ Fruit(){} } class Apple extends Fruit{ Apple(){ super(); } }
