Complete Python Scripting for Automation - Rules to create a pattern Part-2

The video tutorial covers various rules for creating patterns in text processing using regular expressions. It explains the use of symbols like carrot (^) for matching the start of a string, dollar ($) for the end, and slash B (\B) for word boundaries. The tutorial also discusses the significance of using raw strings to handle special characters and provides examples to illustrate these concepts.

What does the caret (^) symbol signify in regular expressions?

• End of a string

• Start of a string

• Middle of a string

• Any position in a string

Which symbol is used to match the end of a string in regular expressions?

• Caret (^)

• Dollar ($)

• Slash B (\b)

• Capital B (\B)

What is the purpose of the slash B (\b) symbol in regular expressions?

• To match the start of a string

• To match non-word boundaries

• To match the end of a string

• To match word boundaries

How can you ensure that special characters are treated as literals in a pattern?

• By using a capital B (\B) symbol

• By using a caret (^) symbol

• By using a raw string

• By using a dollar ($) symbol

In regular expressions, which symbol is used to match a word boundary?

• Caret (^)

• Capital B (\B)

• Dollar ($)

• Slash B (\b)

What does the capital B (\B) symbol represent in regular expressions?

• Word boundaries

• Start of a string

• Non-word boundaries

• End of a string

• \t

• \b

• \n

• \r

What is the function of the \t character in regular expressions?

• Matches a carriage return

• Matches a newline

• Matches a tab

Which character is used to match a newline in regular expressions?

• \n

• \t

• \b

• \r

What does the \r character represent in regular expressions?

• Carriage return

• Tab

• Newline
