如何计算文本文件中值匹配的出现次数

Question

Here's my problem: each employee is uniquely identified by an id (eg KCUTD_41) I have already created a dictionary from a file to gather each company with the employee id and that looks like this:

{    'Company 1' :['KCUTD_41',
                   'KCTYU_48',
                   'VTSYC_48',
                      ......]
     'Company 2' :['PORUH_21',
                   'PUSHB_10',
                    ....... ]
     'Company 3' :['STEYRU_69']}

In total I have several companies.

In parallel in another file, I have several lines where each line corresponds to a collaboration group between companies with several employees and doctoral students (d215485 etc.....)

The file looks like this:

PORUH_21 d215487 d215489 d213654 KCTYU_48 d154225 ...
d25548 d89852 VTSYC_48 d254548 d121154 d258774 PUSHB_10 ...
etc ....

What I want is the number of employees and the number of groups (line where it appears) to get something like that

OUTPUT:

Company 1 : (number of employees from company 1 per line ) : number of groups or line where it appears in total 
Company 2 : (number of employees per line from company2) : nb of groups or line where the employees from company2 appears in total
Company 3 : ......

I wanted to use a condition in order to see if the values for each keys from my dictionary matches and if yes count the number of occurrences

I hope it's better now ^^'

If you can help me ^^

Answer 1

I'm not clear exactly how you want the output to look, but this code might help you get to where you want to go...

import re

companies = {
    'Company 1' :['KCUTD_41','KCTYU_48','VTSYC_48'],
    'Company 2' :['PORUH_21','PUSHB_10'],
    'Company 3' :['STEYRU_69']
     }

finalout = {}
for k,v in companies.items():
    finalout[k] = {"number_in_company":len(v)}
print (finalout)

lines_from_file = [
    "PORUH_21 d215487 d215489 d213654 KCTYU_48 d154225", 
    "d25548 d89852 VTSYC_48 d254548 d121154 d258774 PUSHB_10"
]


pattern_groups    = "(d\d+)"
pattern_employees = "([A-Z]_\d+)"
for line in lines_from_file:
    print("---------------------")
    print(line)
    print("Groups per line:", re.subn(pattern_groups, '', line)[1])
    print("Employees per line:", re.subn(pattern_employees, '', line)[1])

OUTPUT:

{'Company 1': {'number_in_company': 3}, 'Company 2': {'number_in_company': 2}, 'Company 3': {'number_in_company': 1}}
---------------------
PORUH_21 d215487 d215489 d213654 KCTYU_48 d154225
Groups per line: 4
Employees per line: 2
---------------------
d25548 d89852 VTSYC_48 d254548 d121154 d258774 PUSHB_10
Groups per line: 5
Employees per line: 2
