def power (b, e):
“””Return the power value.
b — is the base is the exponent
e–
“””
return b** e
# print docstring of add method
print(add._doc_)
print(power.__doc_)
# print docstring of power method
Q2.1:-L2/Identifiers and Keywords/Understanding Identifiers in Python :- Select all the correct statements from the given options.
We can use any special character like @,#,$ as part of identifiers.
1st string is a valid identifier.
