What Are Strings in Python?

In Python, a string is a type of data used to store text. This can be anything like a company name, a currency symbol, an invoice note, or a financial report.

To create a string, you just put the text inside quotes. You can use either single quotes '...' or double quotes "..." — both work the same.


              12345
            
category = "Office Rent"
amount = "12000 UAH"

print("Expense Category:", category)
print("Amount:", amount)

Double Quotes Help with Apostrophes

If your text includes an apostrophe ', use double quotes to avoid errors:


              12
            
note = "Payment for accountant's services (February)"
print(note)

Multi-line Strings

Sometimes you need to write text on multiple lines — like a short report or a transaction description. In that case, use triple quotes: '''...''' or """...""".


              1234567891011
            
report = """
March Expense Report:

- Office Rent: 12000 UAH
- Salaries: 45000 UAH
- Internet & Phone: 800 UAH

Total Expenses: 57800 UAH
"""

print(report)

If you try to do this with normal quotes, Python will give an error:


              123
            
# This will cause an error:
description = 'Transaction:
Hosting payment for the accounting system.'

Python doesn't allow line breaks inside single-line strings.

Task

Swipe to start coding

Imagine you're tracking the financial state of a company.

If your company's financial report this month is bad, assign "loss" to the variable financial_result; otherwise, assign "profit".
If your mood as an accountant is not great, assign "could be better" to the variable accountant_mood; otherwise, assign "could not be better".
Does your mood depend on the company's finances? If yes — assign "yes" to the variable mood_depends_on_finance; otherwise — assign "no".
