First String

Let's start with a script that creates a string, names it s, and prints it.

Example script: first_string_intro

  • Make sure your micro:bit is connected to your computer and micro:bit programming software ( is used in these screencaptures).
  • Enter this script and save it as first_string_intro.
  • Flash the script into the micro:bit.
# first_string_intro

from microbit import *


s = "ABC 123"
  • Open the Terminal and verify that it displays ABC 123.

How it Works

The statement s = "ABC 123" creates a string variable named s.  The string it refers to contains the characters A B C  1 2 3.  The statement print(s) displays the contents of the string named s.

Did You Know?

A print statement allows you to display more than one string at a time.  You will find it helpful to add a string that explains what's about to be printed.  So, instead of just print(s), you could use print("s = ", s).  This will become important when you write larger scripts.  While adjusting them to work the way you want, you can include information such as the variable name and the location within the the script the print statement is being executed.  Here is an example:

s = "ABC 123"
print("s =", s)


As mentioned earlier, strings can contain multiple lines.

"""This is also a string
 with more than one line
 enclosed by three double-quotes."""


A single line string can also be split up into multiple lines in the Python script.

"This is a string with only one line"\
"that has been split into multiple"\
"lines to fit in your code editor"\


A string in double quotes can contain single quotes:

"This string in double-quotes 'contains' single-quotes."


Strings can also contain escape characters preceded by a backslash to print special-case characters like the tab, apostrophe, and newline.  Here’s an example you will try.  

s4 = 's4 has tab \t apostrophe \', and newline \n...for next line.'

Keep in mind that if the above string was enclosed in double quotes, it would not need the \' to display the apostrophe.
