Python How To Negate A Boolean

When working with Python there are times where you might want to negate a boolean. This is pretty easy to do as python has built in features to handle this. You can do this by using the ‘not’ keyword.

To negate a boolean in Python just use the following example:

print(True)               # prints True
print(not True)         # prints False
print( 5 == 5 )          # prints True
print( not 5 == 5 )    # Prints False

Here is an example showing how you might actually do this.

statusOK = checkDataStatus()

if not statusOK:
    print("Error")
