lua string replace / remove

-- Define the original string
local originalString = "Hello, Lua! Lua is awesome!"

-- Replace occurrences of 'Lua' with 'Python'
local replacedString = originalString:gsub('Lua', 'Python')
print(replacedString)

-- Remove occurrences of 'awesome'
local removedString = replacedString:gsub('awesome', '')
print(removedString)

Explanation:

  1. local originalString = "Hello, Lua! Lua is awesome!": Initializes a string variable named originalString with the value "Hello, Lua! Lua is awesome!".

  2. local replacedString = originalString:gsub('Lua', 'Python'): Uses the gsub function, which stands for "global substitution", to replace all occurrences of the substring 'Lua' with 'Python' in the originalString. The modified string is stored in the variable replacedString.

  3. print(replacedString): Outputs the replacedString to the console, displaying the result of the replacement.

  4. local removedString = replacedString:gsub('awesome', ''): Uses gsub again to replace all occurrences of the substring 'awesome' with an empty string (effectively removing it) in the replacedString. The modified string is stored in the variable removedString.

  5. print(removedString): Outputs the removedString to the console, displaying the result after removing the specified substring.
