Now that you've seen how to display simple messages using the print() function, let's dive into one of the most fundamental data types in Python: strings. Strings are used to represent textual data. Think of them as sequences of characters – letters, numbers, symbols, and spaces – all enclosed within quotation marks.
In Python, you can create strings using either single quotes (') or double quotes ("). Both work equally well, and the choice often comes down to personal preference or the specific characters you're using within the string. If your string needs to contain a single quote, it's often easier to enclose the entire string in double quotes, and vice-versa.
print('This is a string using single quotes.')
print("This is a string using double quotes.")Let's try printing a string with a mix of characters. Notice how the spaces and punctuation are all part of the string!
print("Hello, Python learners! Welcome to chapter 1.")You can also assign strings to variables. This allows you to store and reuse text throughout your program. Variables act like named containers for your data.
greeting = "Hi there!"
name = 'Alice'
print(greeting)
print(name)What happens if you need to include a quotation mark within your string? Python is smart enough to handle this. If you start a string with double quotes, you can include single quotes inside it without any issues. Similarly, if you start with single quotes, you can use double quotes inside.
message1 = "She said, 'Hello!'"
message2 = 'He replied, "Indeed!"'
print(message1)
print(message2)If you need to include the same type of quote character within your string, you'll need to use an 'escape character'. The backslash (\) is Python's escape character. By placing a backslash before the quote, you tell Python to treat that quote as a literal character rather than the end of the string.
