查找2个特定字符之间的字符串

Question

I have a list of directories:

C:\level1\level2\level3\level4\level5\level6\level7

I need a way to extract "level4" and "level5" .

Aka. I need to extract the string between the 4th and 5th backlash and the string between the 5th and 6th backslash.

How would I go about doing this?

Answer 1

Try splitting by backslash :

s = "C:\level1\level2\level3\level4\level5\level6\level7"
l = s.split('\\')
print l[4], l[5]

Answer 2

Use str.split

>>> s = r'C:\level1\level2\level3\level4\level5\level6\level7'
>>> words = s.split('\\') # Escape backslash or use rawstring -  r'\'
>>> words[4]
'level4'
>>> words[5]
'level5'

If you want to join those two words, then use str.join

>>> ' '.join((words[4],words[5]))
'level4 level5'

Also if you want a list of levels,

>>> ' '.join(words[i] for i in [4,5,6])
'level4 level5 level6'

Answer 3

You can use str.split to split a string according to a specific delimiter.

path = r'C:\level1\level2\level3\level4\level5\level6\level7'
dirs  = path.split('\\')

print dirs[4], dirs[5]
# will print:
# level4 level5
