Python splits an integer string and transitions to an integer list

Python regular expression module, split string, Re.split ()

eg

s = ' 1, 2, 3, 4 '

Split up the list of numbers:

STRs = Re.split (', ', s);

Print (STRs);

Results: [' 1 ', ' 2 ', ' 3 ', ' 4 ']

Go to int line list:

STRs = list (map (int, strs));

Print (STRs);

Results: [1, 2, 3, 4]

If there is more than one delimiter in the STRs, the middle of the pattern string applies the ' | ' Separate delimited characters (or delimited strings):

eg

STRs = ' [112, 236, 372; 131] ';

STRs = Re.split (', |; |\[|\] ');

Print (STRs);

Result: [' ', ' 112 ', ' 236 ', ' 372 ', ' 131 ', ']

To remove the null and void string:

Strs.remove ("); # # #一次只能去除一个空串
