Store Text with Strings in Python
To store text in Python, you need to enclose it in quotation marks. For example, you can store the word "Python" in the language variable.
# Save string within variable language = 'Python' # Output string print(language)
Variables that store text are called strings. A string is a sequence of characters enclosed in single (') or double (") quotes.
Even if a string contains numbers, it's treated as text, so you cannot perform math operations on it directly. To use a number from a string in calculations, convert it to a numeric type first.
# Assigning a numeric value as a string to the variable 'hour' hour = '16' # Printing the value stored in 'hour' print(hour)
Sometimes you may need to include a quote inside the string itself. In that case, use the backslash (\) to escape it.
# Use `\` to escape quotes inside string quote = 'She said, \"It\'s a wonderful day!\"' # Printing the `quote` print(quote)
