代码如下：

author = 'damao'

import os

"""
join()函数
语法：str.join(item)
join是一个字符串操作函数，

"""
# 分隔符
seq1 = ['hello','good','boy','doiido']
print(' '.join(seq1))
print('@ '.join(seq1))

# 对字符串进行操作
seq2 = "hello good boy doiido"
print(','.join(seq2))
# print(list(seq2.split()))

# 对元组进行操作
seq3 = ('hello','good','boy','doiido')
print(','.join(seq3))

# 对字典进行操作
seq4 = {'hello':'1','good':'2','boy':'3','doiido':'4'}
a = []
for i in seq4:
    # print(seq4[i])
    a.append(''.join(seq4[i]))
    # print(','.join(seq4[i]))
print(a)
# print(seq4.get())

# 合并目录
a = os.path.join('/aaa/','aa/bb/','cccc')
print(''.join(a))
