Question

How do you find the length of a string?

Short answer

Answer: To find the length of a string in Python, you can use the built-in len() function by passing the string as an argument, like this: len(string). Special characters, such as newline (\n) and tab (\t), are counted as one character each, and they do affect the length of the string.

Step-by-step solution

1. Introduction to Strings in Python

In Python, strings can be represented using single quotes (' ') or double quotes (" "). For example, the string "Hello, World!" can be represented in Python as 'Hello, World!' or "Hello, World!". To find the length of a string in Python, we can use the built-in len() function.

2. Using the len() function to find the length of a string

The len() function in Python takes a string as its input and returns the number of characters in that string. To use the len() function, simply pass the string as an argument to the function, like this: len(string). Here's an example to find the length of the string "Hello, World!": ```python string = "Hello, World!" length = len(string) print(length) # Output: 13 ``` In this example, we have a string "Hello, World!" and we pass it as an argument to the len() function. The function returns the number of characters in the string, which is 13 in this case. Finally, we print the result, which shows the length of the string.

3. Handling strings with special characters

Keep in mind that some characters in a string might be escape characters, such as a newline (\n) or tab (\t). These characters still count as one character each, but they might not be visible when the string is printed. For example: ```python string_with_newline = "Hello,\nWorld!" length_with_newline = len(string_with_newline) print(length_with_newline) # Output: 13 ``` Here, the string has a newline character (\n) that separates "Hello," and "World!". When passed to the len() function, it still counts as one character, and the total length of the string is 13.
