Repl Vs Scripts - Pycom WiPy 3.0 Manual

9.3 REPL vs Scripts
REPL vs Scripts
Users of this documentation should be aware that examples given in the docs are under the
expectation that they are being executed using the MicroPython REPL. This means that
when certain functions are called, their output may not necessarily be printed to the console
if they are run from a script. When using the REPL many classes/functions automatically
produce a printed output displaying the return value of the function to the console. The code
snippet below demonstrates some examples of classes/functions that might display this
behaviour.
Basic Arithmetic
1 + 1 # REPL will print out '2' to console
1 + 1 # Script will not return anything the console
print(1 + 1) # Both the REPL and a script will return '2' to the console
Calling Methods
import ubinascii
ubinascii.hexlify(b'12345') # REPL will print out "b'3132333435'" to the console
ubinascii.hexlify(b'12345') # Script will not return any the console
In order to use these functions that do not print out any values, you will need to either wrap
them in a statement or assign them to variables and call them later when you wish
print()
to use them.
For example:
# immediately print to console when using a script
print(1 + 1)
# or save variable to for later
value = 1 + 1
# do something here...
print(value)
