将gsub命令从R转换为Python

Question

I want to split this mystring="0G15^GAC0T60T4^AA0C0" and get the following output with python:

['0','G','15','^GAC','T','60','T','4','^AA','C']

It could be done with this command in R:

mystring <- "0G15^GAC0T60T4^AA0C0"
gsub("([\\^]*[ACGT]+)[0]*", " \\1 ", mystring)

how can I translate the R script into python?

Thanks

Answer 1

You can reuse your existing regular expression using Pythons re module

import re

mystring = "0G15^GAC0T60T4^AA0C0"
l = re.sub("([\\^]*[ACGT]+)[0]*", " \\1 ", mystring).split()

l is then

['0', 'G', '15', '^GAC', 'T', '60', 'T', '4', '^AA', 'C']

Answer 2

You can try this:

mystring="0G15^GAC0T60T4^AA0C0" 
import re
new_data = re.findall('(?<!\^[GAC])\d+|(?<!\^)\w|\^[a-zA-Z]+', mystring)
final_data = [a for i, a in enumerate(new_data) if a != '0' or not new_data[i-1].startswith("^")][:-1]

Output:

['0', 'G', '15', '^GAC', 'T', '60', 'T', '4', '^AA', 'C']
