This article mainly shows you "Python has join() and os.path.join() two functions what is the use of", the content is simple and easy to understand, organized clearly, I hope to help you solve doubts, let Xiaobian lead you to study and learn "Python has join() and os.path.join() two functions what is the use of" this article bar.

Python has join() and os. path. join() functions, which do the following:

join(): join string arrays. concatenates elements in a string, tuple, or list with a specified character (delimiter) to generate a new string

os.path.join(): Return after combining multiple paths

Operates on sequences (using ' ' and ':' as delimiters, respectively)

>>> seq1 = ['hello','good','boy','doiido']>>> print ' '.join(seq1)hello good boy doiido>>> print ':'.join(seq1)hello:good:boy:doiido

Manipulate on strings

>>> seq2 = "hello good boy doiido">>> print ':'.join(seq2)h:e:l:l:o: :g:o:o:d: :b:o:y: :d:o:i:i:d:o

Manipulate on tuples

>>> seq3 = ('hello','good','boy','doiido')>>> print ':'.join(seq3)hello:good:boy:doiido

operating on dictionaries.

>>> seq4 = {'hello':1,'good':2,'boy':3,'doiido':4}>>> print ':'.join(seq4)boy:good:doiido:hello

merged directory

>>> import os>> os.path.join ('/hello/','good/boy/',' doido')'/hello/good/boy/doido')'/hello/good/boy/doido', above is "Python has join() and os.path.join() two functions have what to use" All the contents of this article, thank you for reading!
