As a Python dev, we have probably been exposed to many ways of converting from one data type to another. Today we will show you how to convert NoneType to an integer in Python. Read on for more details.
Convert NoneType to an integer in Python
NoneType is the data type for the None object. It indicates that the object has no value at all.
We will show you the three simple ways to convert NoneType to an integer in Python.
try: # Code except: # Executed if there is an error in the try block
First, the code in the
try block is executed.
Then if no error occurs, the
except block is ignored, and the program will continue.
If an error occurs while executing the code in the
try block, the program will ignore the code below it, and the
except clause will execute.
If any exception occurs, the
except clause still doesn’t handle it. So the program will stop executing.
This concept is often used in Python to handle exceptions. In this case, we use
try...except to cast a NoneType to integer. If it cannot be cast, assign it any number. See the sample code below for a better understanding.
nothing = None try: nothing = int(nothing) except TypeError: nothing = 0 print(nothing)
if condition: # Body of if else: # Body of else
if…else statement, they have two cases (True or False). The
if block will be executed when the condition is valid. The
else block will be executed when the condition is invalid.
if…else to check if a variable is of type NoneType using
is operator. If true, assign it to any int. Otherwise, keep the value because it’s not NoneType.
nothing = None if nothing is None: nothing = 0 else: nothing print(nothing)
Or we can write more succinctly. Like this:
nothing = None nothing = 0 if nothing is None else nothing print(nothing)
Using OR operator
<expression1> or <expression2>
OR operator finds the first truthy value in the
OR expression. If there is no truthy value, it will return the last value.
We will check whether our value is Truthy or Falsy. If our value is None, then the
OR operator will ignore it and replace it with 0. Like this:
nothing = None nothing = nothing or 0 print(nothing)
