Slice the Word

Slicing allows you to extract a substring — a sequence of characters from a string. Unlike indexing (which gives one character), slicing returns a portion of the string.

python

start — the index where the slice begins (inclusive)

end — the index where the slice stops (exclusive)

So the character at start is included, but the character at end is not.


              
123

            
record = "Invoice INV-2024-007 paid"
invoice_code = record[8:21]
print(invoice_code)  # Output: INV-2024-007
copy

In this case:

  • 'I' is at index 8;
  • '7' is at index 20;

So we use [8:21] to get the full invoice code

Oppgave

Given the string:

"asset and liability, debit and credit"

  1. Use slicing to extract the word "asset" and assign it to the variable asset.

  2. Use slicing to extract the word "debit" and assign it to the variable debit. Make sure to use slicing only — no string methods or manual typing.
