Your Turn: String to Int, Math and Back

You may have already seen how to get a string and convert it to int in the Computer–micro:bit Talk tutorial.  Here, the int result after calculations is also converted back to a string.

Example script: convert_your_turn

• Enter, name, and save convert_your_turn.  
• Click the Send to micro:bit button.

# convert_your_turn

from microbit import *

sleep(1000)

s = "1234"
print("Before int conversion:")
print("s =", s)
print()

n = int(s)   # convert to int

n2 = n + n   # add

s2 = str(n2) # convert back

print("After convert, add ints, convert back:")
print("s2 =", s2)

• Check the results in the serial monitor.
• Verify that the resulting s2 string contains the characters “2468”  that represent the result of adding two 1234 int values together.
