[Python] How do I change a property in a Python function to be optional?

**I want to make a module. The modules can easy to use Python. But I'm in trouble. The code is:

class EasyPy:

def easy_print(self, condition, implementation):
if implementation is None:
implementation = False
print(condition)
if condition:
a = implementation


I invoke this class:

b=EasyPy()
b.easy_print(1)


BUT IT REPORTED AN ERROR:

Traceback (most recent call last):
File "I:\PycharmProjects\easypy\easypy.py", line 12, in <module>
b.eprint(1)
TypeError: eprint() missing 1 required positional argument: 'implementation'


I changed the program：

class EasyPy:

def easy_print(self, condition, implementation):
try:
if condition:
a = implementation
except:
if implementation is None:
implementation = False
print(condition)


But it still reported an error：

Traceback (most recent call last):
File "I:\PycharmProjects\easypy\easypy.py", line 12, in <module>
b.eprint(1)
TypeError: eprint() missing 1 required positional argument: 'implementation'
