How to add space after comma if it has letters on each side in a string using RegEx(Java)-CodePudding

Example String = "abcd,anhdc,bajb,abchb,njacsn,10,000,nijaxiu"

Result = "abcd, anhdc, bajb, abchb, njacsn, 10,000, nijaxiu"

Space should not be there after 10, as it is Integer

You didn't mention which environment you are attempting to solve this problem in. So the following answer is written with the assumption that you are working with Python.

Example string:

abcd,anhdc,bajb,abc1hb,nj2acsn,10,000,nijaxiu

This code in Python should get the job done:

import re

s  = "abcd,anhdc,bajb,abc1hb,nj2acsn,10,000,nijaxiu"

blocks = re.findall('[a-zA-Z0-9] ', s)
seperated_blocks = ''
seperated_blocks  = blocks[0]   ','

for idx in range(1, len(blocks), 1):
  if re.match('\d ', blocks[idx-1]) and re.match('\d ', blocks[idx]):
    seperated_blocks  = blocks[idx] ','
  else:
    seperated_blocks  = ' '   blocks[idx] ','

seperated_blocks = seperated_blocks[0:-1]

Output:

'abcd, anhdc, bajb, abc1hb, nj2acsn, 10,000, nijaxiu'

CodePudding user response：

Shouldn't your result be

abcd, anhdc, bajb, abchb, njacsn,10,000, nijaxi

If this is the output you require and you don't mind making a new string then you can simply use the following code:

s = "abcd,anhdc,bajb,abchb,njacsn,10,000,nijaxiu"
new_s = ""
for i in range(len(s)-1):
    new_s  = s[i]
    if(s[i] == ',' and s[i 1].isalpha()):
        new_s  = " "
print(new_s)
