Answer 1

Answer:

Search using literal characters:

• The characters sequence or a character whatever you want to find in the data provided by you will be acting as literal characters
• In the script provided by you, The search is for the all non alphanumeric characters
• All the special characters found in the given paragraph will be identified through the given regular expression syntax and stored in the results array
• Sequence and ranges
• A group of characters from starting character to the ending character, A value between the given minimum and maximum value will be founded by using the sequences and ranges
• In the given solution the the findall function is written for finding the sit [-:] amet , here the range function acts like any character placed in between the two strings in the given literals will be identified and stored in occurences_sit_amit
• so, for the given range of literals '- :' the occurences will be in identified in the given sequence sit-amet
• Special characters and wildcards
• Except a-z,A-Z,0-9 any other character is identified as a special character
• usually the characters like @#$%;, will be treated as special characters
• In the above solved example the findall finds the all the instances of the ant special character except the aplphabets or numbers
• The regular expression excludes all the alphanumeric characters and stores all the remaining characters
