Coding in Python: a comprehensive Beginners Guide to Learn the Realms of Coding in Python

Function and Dictionary
You can pair up a dictionary with a function. Take the example of the
following function.
def user_info(username, gender, email_id):
user = {'uname': username, 'gender': gender, 'email address': email_id}
return user
newuser = user_info('Johnson', '[e-mail]', 'male')
print(newuser)
newuser1 = user_info('John', '[e-mail]', 'male')

---

print(newuser1)
newuser2 = user_info('Jimmy', '[e-mail]', 'male')
print(newuser2)
newuser3 = user_info('Dora', '[e-mail]', 'female')
print(newuser3)
= RESTART: C:/Users/saifia computers/Desktop/sample.py
{'uname': 'Johnson', 'gender': '[e-mail]', 'email address': 'male'}
{'uname': 'John', 'gender': '[e-mail]', 'email address': 'male'}
{'uname': 'Jimmy', 'gender': '[e-mail]', 'email address': 'male'}
{'uname': 'Dora', 'gender': '[e-mail]', 'email address': 'female'}
>>>
The function user_info takes the requisite information about the name, gender
and email address of a user, and fill them up into a dictionary. Each value is
stored in the designated key. The function receives information in raw form
and turns it into textual information in a meaningful data structure. Up till
now, I have stored and processed the information in the form of strings. You
may confront situations where you have to store data in numerical form as
well. There is an easy way out.
def user_info(username, gender, email_id, age=''):
user = {'uname': username, 'gender': gender, 'email address': email_id}
if age:
user['age'] = age
return user
newuser = user_info('Johnson', '[e-mail]', 'male', age=55)
print(newuser)
newuser1 = user_info('John', '[e-mail]', 'male', age=33)
print(newuser1)
newuser2 = user_info('Jimmy', '[e-mail]', 'male', age= 54)

---

print(newuser2)
newuser3 = user_info('Dora', '[e-mail]', 'female', age= 24)
print(newuser3)
= RESTART: C:/Users/saifia computers/Desktop/sample.py
{'uname': 'Johnson', 'gender': '[e-mail]', 'email address': 'male',
'age': 55}
{'uname': 'John', 'gender': '[e-mail]', 'email address': 'male', 'age': 33}
{'uname': 'Jimmy', 'gender': '[e-mail]', 'email address': 'male', 'age':
54}
{'uname': 'Dora', 'gender': '[e-mail]', 'email address': 'female', 'age':
24}

I have added a new parameter to the function's definition and have also
assigned this parameter a kind of empty default value.
