Write a Python program to add, subtract, multiply and division of two complex numbers.

Sample Solution:-

Python Code:

print("Addition of two complex numbers : ",(4+3j)+(3-7j)) print("Subtraction of two complex numbers : ",(4+3j)-(3-7j)) print("Multiplication of two complex numbers : ",(4+3j)*(3-7j)) print("Division of two complex numbers : ",(4+3j)/(3-7j))

Sample Output:

Addition of two complex numbers : (7-4j) Subtraction of two complex numbers : (1+10j) Multiplication of two complex numbers : (33-19j) Division of two complex numbers : (-0.15517241379310348+0.6379310344827587j)

How do I merge two dictionaries in a single expression in Python?

For dictionaries x and y, z becomes a shallowly merged dictionary with values from y replacing those from x.

• In Python 3.5 or greater:
z = {**x, **y}
• In Python 2, (or 3.4 or lower) write a function:
def merge_two_dicts(x, y): z = x.copy() # start with x's keys and values z.update(y) # modifies z with y's keys and values & returns None return z

and now:

z = merge_two_dicts(x, y)
• In Python 3.9.0a4 or greater (final release date approx October 2020): PEP-584, discussed here, was implemented to further simplify this:
z = x | y # NOTE: 3.9+ ONLY

Explanation

Say you have two dicts and you want to merge them into a new dict without altering the original dicts:

The desired result is to get a new dictionary (z) with the values merged, and the second dict's values overwriting those from the first.

A new syntax for this, proposed in PEP 448 and available as of Python 3.5, is

And it is indeed a single expression.

Note that we can merge in with literal notation as well:

and now:
