作业一的代码如下：

f=open('作业素材.txt',encoding='gbk')

txt=f.read()

f.close()

index=txt.find('\n顺丰控股股份有限公司')

txt_target=txt[:index]

lines=txt_target.split('\n')

last_line=lines[-1]

words=last_line.split(' ')

last_word=words[-1]

for i in range(1,len(last_word)):

last_character=last_word[-i]

if last_character.isalpha():

last_word=last_word[:-i+1]

break

if i==len(last_word):

last_word=words[-2]

print(last_word)

print(len(last_word))
