我有清单

['Q 0006 005C 0078 0030 0030 0033 0034 ONE_OF 0002 ']

如何移除最后一个元素Q和0002？

Answer 1

如果您的列表存储在my_list下，那么这应该可以。

my_list = my_list[1:-1]

Answer 2

我不确定你想要什么，因为它不清楚，但这应该有所帮助。实际上，该列表中只有一个元素。

假设您的所有列表项都是以空格作为分隔符的字符串，以下是如何从列表中的每个字符串中删除第一组和最后一组字符。

>>> L = ['Q 0006 005C 0078 0030 0030 0033 0034 ONE_OF 0002 ']
>>> [' '.join(el.split()[1:-1]) for el in L]
['0006 005C 0078 0030 0030 0033 0034 ONE_OF']

Answer 3

#initialize 2 lists what will hold your integers
List1 = []
List2 = []

# prompt the user to enter the integers in the list
List1 = eval(input("Enter the list of integers:")

#Iterate over the list to remove the first and last integer
for i in range(len(List1):
    List2 = list1[1:-1]

#print the contents of your new list to verify the results
print(List2) # the output shouldn't contain first and last integer of List1

Answer 4

# prompt the user to enter the integers in the list
List1 = eval(input("Enter the list of integers:")

#Iterate over the list to remove the first and last integer
for i in range(len(List1):
    List2 = list1[1:-1]

#print the contents of your new list to verify the results
print(List2) # the output shouldn't contain first and last integer of List1
