Strings are an essential part of any programming language, and MicroPython on Raspberry Pi Pico is no exception. They can contain a sequence of characters and can be used for a variety of purposes, from storing user input to displaying information on the screen. One of the useful operations that can be performed on strings is splitting them into smaller pieces. In this blog post, we will explore how to split strings in MicroPython on Raspberry Pi Pico.
The split() method in MicroPython is used to split a string into a list of substrings based on a delimiter. A delimiter is a character that separates each substring in the original string. The syntax for the split() method is as follows:
string.split(delimiter, maxsplit)where string is the original string, delimiter is the character used to separate the substrings, and maxsplit is the maximum number of splits to be performed.
Let’s take a look at an example:
string = "apple,banana,orange"
fruits = string.split(",")
print(fruits)In this example, we define a string string that contains a list of fruits separated by commas. We then use the split() method to split the string into a list of substrings based on the comma delimiter. The resulting list fruits contains the substrings as individual elements:
['apple', 'banana', 'orange']We can also specify the maximum number of splits to be performed. For example:
string = "apple,banana,orange"
fruits = string.split(",", 1)
print(fruits)In this example, we specify a maximum of one split. The resulting list fruits contains the first substring before the comma as the first element and the remaining string as the second element:
['apple', 'banana,orange']It’s important to note that the split() method in MicroPython returns a list of substrings. Each substring is a separate element in the list, which can be accessed using indexing. For example:
string = "apple,banana,orange"
fruits = string.split(",")
print(fruits[0]) # Output: apple
print(fruits[1]) # Output: bananaIn conclusion, splitting strings is a useful operation when working with strings in MicroPython on Raspberry Pi Pico. It allows you to break down a string into smaller pieces and process each piece individually. By using the split() method, you can split a string into a list of substrings based on a delimiter, which can be used for further manipulation in your code.
