Split python multi-space string

The problems to be dealt with in this article are:

A string is divided by multiple blanks of different lengths. I need to remove the spaces and leave useful information to form a list.

For example, "aa bbbbb ccc d"-"['aa',' bbbbb', 'ccc',' d']

Practice

1.str.split ()

2.filter (None,str.split ("))

It is not possible to directly use str.split (""). It can only split a space, as follows.

Def test_filter (): str = "aa bbbbb ccc d" str_list = str.split (") print str_list

Results:

The first approach

In fact, the split () function can split by space by default and delete the empty string in the result, leaving useful information

Def test_filter (): str = "aa bbbbb ccc d" str_list = str.split () print str_list

Results:

The second approach

You can filter split ("") with the filter function

Def test_filter (): str = "aa bbbbb ccc d" str_list = filter (None,str.split (")) print str_list

Results:

When the first parameter of filter is None, the non-null value of the second parameter is returned.

Perhaps the first method is more convenient.

How to split a string

There are few examples that show you how to split a string into lists in Python.

1. Split by SPAC

By default, split () uses spaces as delimiters.

Alphabet = "ab c d e f g" data = alphabet.split () # split string into a list for temp in data: print temp

Output quantity

A

B

C

D

E

F

G

two。 Segmentation + maximum segmentation

Split only by the first 2 spaces.

Alphabet = "ab c d e f g" data = alphabet.split ("", 2) # maxsplit for temp in data: print temp

Output quantity

A

B

C d e f g

3. Split with #

Another example.

Url = "mkyong.com#100#2015-10-1" data = url.split ("#") print len (data) # 3print data [0] # mkyong.comprint data [1] # 100print data [2] # 2015-10-1 for temp in data: print temp

Output quantity
