basic concepts
The os.path.split () divided by the path name of the one pair of the head and tail of the list. Yes tail of the list of last pathname elements. head element is in front of it.
for example:
path name = '/home/User/Desktop/file.txt'
In the above example, the path name is called tail file.txt path '/ home / User / Desktop / ' called the head. tail part will never contain a slash symbol. If this path name ends with a slash, then the tail is empty.
If there is no slash in the path, then the head is empty. Here are the detailed parameters:
path head tail
'/home/user/Desktop/file.txt' '/home/user/Desktop/' 'file.txt'
'/home/user/Desktop/' '/home/user/Desktop/' {empty}
'file.txt' {empty} 'file.txt'
Case Analysis
1 Example one:
# Python program to explain os.path.split() method
# importing os module
import os
# path
path = '/home/User/Desktop/file.txt'
# Split the path in
# head and tail pair
head_tail = os.path.split(path)
# print head and tail
# of the specified path
print("Head of '% s:'" % path, head_tail[0])
print("Tail of '% s:'" % path, head_tail[1], "\n")

# print head and tail
# of the specified path
print("Head of '% s:'" % path, head_tail[0])
print("Tail of '% s:'" % path, head_tail[1])
2 results:
Head of '/home/User/Desktop/file.txt': /home/User/Desktop
Tail of '/home/User/Desktop/file.txt': file.txt
Head of '/home/User/Desktop/': /home/User/Desktop
Tail of '/home/User/Desktop/':
Head of 'file.txt':
Tail of 'file.txt': file.txt
