如何从列表中的列表中删除项目？

Question

我有这个代码，想从列表中删除'和'

def names_to_apa(names):
    x = names.split(",")  
    nm = []
    for y in x:
        nm.append(y.split())
    print(nm)
    for i in nm:
        if i == 'and':
            nm.remove(i)
    print(nm)

print(names_to_apa("First Last, David Joyner, and George Burdell"))
#print: Last, F., Joyner, D., & Burdell, G.

电流输出为：

[['First', 'Last'], ['David', 'Joyner'], ['and', 'George', 'Burdell']]

但我想去掉第三张单子上的and

我所做的尝试不起作用，而且我通过搜索StackOverflow找到的似乎只适用于单个列表，或者我不知道如何在列表中的列表中实现它

你能帮忙吗

Answer 1

您需要访问子列表来执行删除操作，而不是访问外部列表：

data = [['First', 'Last'], ['David', 'Joyner'], ['and', 'George', 'Burdell']]

for sublist in data:
    while "and" in sublist:
        sublist.remove("and")

Answer 2

尝试此操作您可以在代码中添加一条指令，将“and”替换为“”：

def names_to_apa(names):
    names=names.replace("and","")
    x = names.split(",")
    nm = []
    for y in x:
        nm.append(y.split())
    print(nm)
    for i in nm:
        if i == 'and':
            nm.remove(i)
    print(nm)

print(names_to_apa("First Last, David Joyner, and George Burdell"))

输出：

[['First', 'Last'], ['David', 'Joyner'], ['George', 'Burdell']]
