How to define stings and integer literals in Python while creating a code?

Answer 1

Strings can be converted to numbers by using the int() and float() methods. If your string does not have decimal places, you'll most likely want to convert it to an integer by using theint() method. Because the two numeric values were stored in strings, we received an error

Answer 2

Not sure what you mean by "define"here ...

"This is a sentence" # string literal
12345 # integer literal
123.45 # floating point literal

Literals are values of a certain type, and can be assigned to variables, used in comparison etc. Literals cannot be changed, until they are stored in a variable.
