I want to extract the values of the below text

Pafient Name : Thomas Joseph MRNO : DQ026151?
Doctor : Haneef M An : 513! Gandar : Male
Admission Data : 19-Feb-2V'3‘¥T12:2'$ PM Bill No : IDOGIII.-H-17
Discharge Date : 22-Feb-20$? 1D:5‘F AM Bill Dale : E2-Feb-2017

extract only the values of the field names for example,

Thomas Joseph from the field name Pateint name, similarly for others field names and save the output to excel

Python code for the above

My attempt -

text = pt.image_to_string(img1)
print(text)
s = re.findall(r'\s:\s(\w+)', text)
print (s)

  • $\begingroup$ This job would be quite easier if you know what fields you will have in the text. $\endgroup$

    $\begingroup$ I'm voting to close this question as off-topic because this is just a python regex question and you'd get a quicker answer on StackOverflow. $\endgroup$

It may not be perfect but does the job almost. 

import re
re.findall(r'(?<=: )\w{2}-\w{3}-\d{4}|(?<=: )\d{2}-\w{3}-\w{2}|(?<=: )\s?\w+\s?\w+\s?\w+',data)

#['Thomas Joseph MRNO','DQ026151','Haneef M An','513','Male','19-Feb-2V','IDOGIII','22-Feb-20','E2-Feb-2017']

As @spacedman correctly mentioned, this will answered quicker at StackOverflow. But you can use this to create a dictionary like this. There might be a better way but this is a quick work around.

# -*- coding: utf-8 -*-
import re
st = '''Pafient Name : Thomas Joseph MRNO : DQ026151?
Doctor : Haneef M An : 513! Gandar : Male
Admission Data : 19-Feb-2V'3‘¥T12:2'$ PM Bill No : IDOGIII.-H-17
Discharge Date : 22-Feb-20$? 1D:5‘F AM Bill Dale : E2-Feb-2017'''
st = st.decode('utf-8').replace('\n','')+'<eof>'
words = ['Pafient Name','MRNO','Doctor','An','Gandar','Admission Data','PM Bill No','Discharge Date','Bill Dale','<eof>']
print {words[i]:st[st.index(words[i])+len(words[i]):st.index(words[i+1])].replace(':','').strip() for i in range(len(words)-1)}

  • $\begingroup$ Try it in python 2.7, you might be using 3.x. Either way remove the dictionary comprehension and write a normal loop and try to print the substrings and then debug and find the type of error. This should give u some clue. $\endgroup$
