Summary

Application that takes a string or file and returns the number of all characters in the string or file occurring only once. The function was tested using pytest. The function is in the single_char_counter_by_ng folder and the tests are in the tests folder. The test_count_single_char folder contains tests and parameterized data. For convenience, some __init__ already have modules imported.

Usage

from single_char_counter_by_ng import (count_single_char, 
                                       count_single_char_in_file)

count_single_char('HelLo') # ---> 5

count_single_char('HelLo', case_insensitive=True) # ---> 3

# file.txt ---> 'HelLo'
count_single_char_in_file('path_to_file/file.txt') # ---> 5

count_single_char_in_file('path_to_file/file.txt', case_insensitive=True) # ---> 3

Also implemented command-line interface(CLI):

python count_single_char.py --string “your string”

python count_single_char.py -s “your string”

or

python count_single_char.py --file "path_to_text_file"

python count_single_char.py -f "path_to_text_file"

There is also a "-i" parameter that can be specified so that the result is case insensitive:

python count_single_char.py -s “your string” -i

If you passed two parameters, the parameter '--file' have higher priority:

python collect_framework.py  --string “your string” --file path_to_text_file
