Introduction to strings in MicroPython on Raspberry Pi Pico

Strings are a fundamental data type in programming, and they are no exception in MicroPython on Raspberry Pi Pico. A string is a sequence of characters enclosed in single or double quotes. Strings are used to represent text in programs, and they can be manipulated in various ways to achieve different results.

In this blog post, I will introduce you to strings in MicroPython on Raspberry Pi Pico. We will cover the basic concepts and syntax of strings, and provide examples of how to use them in your programs.

Basic syntax of strings in MicroPython

To create a string in MicroPython, simply enclose the text in single or double quotes. For example, the following line creates a string containing the text “Hello, world!”:

my_string = "Hello, world!"

You can also create an empty string by assigning an empty pair of quotes to a variable, like this:

empty_string = ""

String operations in MicroPython

Strings can be concatenated, sliced, and indexed in MicroPython, just like in any other programming language. Here are some examples:

Concatenation:

string_1 = "Hello"
string_2 = "world"
string_3 = string_1 + ", " + string_2 + "!"
print(string_3)

Output: Hello, world!

Slicing:

my_string = "Hello, world!"
print(my_string[0:5])

Output: Hello

Indexing:

my_string = "Hello, world!"
print(my_string[7])

Output: w

String methods in MicroPython

MicroPython provides a set of built-in string methods that allow you to manipulate strings in various ways. Here are some examples:

Length:

my_string = "Hello, world!"
print(len(my_string))

Output: 13

Upper case:

my_string = "Hello, world!"
print(my_string.upper())

Output: HELLO, WORLD!

Lower case:

my_string = "Hello, world!"
print(my_string.lower())

Output: hello, world!

Splitting:

my_string = "Hello, world!"
print(my_string.split())

Output: [‘Hello,’, ‘world!’]

Conclusion

Strings are a powerful and versatile data type in programming, and understanding how to use them is essential for any programmer. In this blog post, we have introduced you to strings in MicroPython on Raspberry Pi Pico. We have covered the basic concepts and syntax of strings, as well as provided examples of string operations and methods. With this knowledge, you can begin working with strings in your own MicroPython programs.
