Python's method of dividing string equal lengths: 1. Split two in groups, the code is [b=(r'.{2}',aa)]; 2. Split three characters in a string according to a fixed length, the code is [(r'.{3}',string)】。

Python method to split string equal length:
Method 1:
Code Example #!/bin/python
#site:WWW.
#
A = open('','r')
a = ()
for aa in a:
b = list(())
c=''
for i in range(len(b)):
if i !=0:
if i%2 == 0:
c=c+'-'+b[i]
else:
c=c+b[i]
else:
c=c+b[i]
print c
()
Method 2:
Code Example #!/bin/python
#
import re
A = open('','r')
a = ()
for aa in a:
b=(r'.{2}',aa)
c='-'.join(b)
print c
()
Using python regular expressions is implemented, the execution efficiency is high and worth recommending.

Python is still very awesome in handling strings, and it is recommended that you master it firmly.
Python splits a string with a set of three characters according to a fixed length
Code one def cut_text(text,length):
textArr = ('.{'+str(lenth)+'}', text)
(text[(len(textArr)*lenth):])
return textArr
print(cut_text('123456789abcdefg',3))
['123', '456', '789', 'abc', 'def', 'g']
Code 2 >>> import re
>>> string = '123456789abcdefg'
>>> (r'.{3}', string)
['123', '456', '789', 'abc', 'def']
