Python 如何使用splice删除字符串的最后一个字符

比如说我有字典， 如何编写代码以使其生成

dictionar
dictiona
diction
dictio
dicti
dict
dic
di
d

（删除最后一个字符）

我目前有：

def generate_letter_removed(word):
    return_list4 = []
    for i in range(1, len(word)):
        q = word[:-1]
        return_list4.append(q)
    return return_list4

letter_removed = generate_letter_removed(word)
print(letter_removed)

但这会产生“字典”

更正您的代码

def generate_letter_removed(word):
    return_list4 = [word]
    for i in range(1, len(word)):
        q = word[:-i]
        return_list4.append(q)
    return return_list4
word=input("Enter A Word: ")
letter_removed = generate_letter_removed(word)
print(letter_removed)

输出

使用字符串切片：

word = "dictionary"
for i in range(len(word), 0, -1):
    print(word[:i])

输出：

dictionary
dictionar
dictiona
diction
dictio
dicti
dict
dic
di
d

作为一项功能：

def slice_output(w):
    print('\n'.join(w[:i] for i in range(len(w), 0, -1)))

def slice_output(w):
    print('\n'.join(w[:i] for i in range(len(w), 0, -1)))
