python reverse 和reversed 區別

1，reverse是list的內置方法，reversed是個函數

2，reverse是改變原來的list,

def list1(list_num):
    list_num.reverse()#此處相當於把list_num 逆置了
    return list_num
print(llist1(['q','w','f']))

reversed 則是變成一個迭代器

# "Let's take LeetCode contest"
# 輸出: "s'teL ekat edoCteeL tsetnoc"
def str01(st):
     # return ' '.join([ i[::-1] for i in st.split(' ') ]
     # return ' '.join(st[::-1].split(' ')[::-1])
     list1=st[::-1].split(' ')
     list1.reverse()
     return ' '.join(list1)
     # return ' '.join(list(reversed(st[::-1].split(' '))))
if __name__ == '__main__':
    print(str01("Let's take LeetCode contest"))
