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

Returning Values
A function does not have to display the output in a direct form. You can
make the function process a bunch of data and return the value in an indirect
form. The return statement picks up a value from the function and forwards it
to the line that made a function call.
def user_info(username, email_id ):
info = "My name is " + username.title() + " and I am a new user, and my
email ID is " + email_id.title() + "."
return info.title()
newuser = user_info('Dora', '[e-mail]')
print(newuser)
newuser1 = user_info('John', '[e-mail]')
print(newuser1)
newuser2 = user_info('Jimmy', '[e-mail]')
print(newuser2)
= RESTART: C:/Users/saifia computers/Desktop/sample.py
My Name Is Dora And I Am A New User, And My Email Id Is
[e-mail].
My Name Is John And I Am A New User, And My Email Id Is
[e-mail].

---

My Name Is Jimmy And I Am A New User, And My Email Id Is
[e-mail].

In the next code sample, I will add another argument to the code. I will also
experiment on making an argument optional so that the users who do not
want to fill in a value, can leave it without running an error in the program.
def user_info(username, email_id, gender ):
info = "My name is " + username.title() + " and I am a new user, and my
email ID is " + email_id.title() + ". My gender is " + gender.title() + "."
return info.title()
newuser = user_info('Dora', '[e-mail]', 'female')
print(newuser)
newuser1 = user_info('John', '[e-mail]', 'male')
print(newuser1)
newuser2 = user_info('Jimmy', '[e-mail]', 'male')
print(newuser2)
= RESTART: C:/Users/saifia computers/Desktop/sample.py
My Name Is Dora And I Am A New User, And My Email Id Is
[e-mail]. My Gender Is Female.
My Name Is John And I Am A New User, And My Email Id Is
[e-mail]. My Gender Is Male.
My Name Is Jimmy And I Am A New User, And My Email Id Is
[e-mail]. My Gender Is Male.

Suppose someone wants to leave the email option aside. You can add a
conditional statement to the existing code to allow users to make a choice at
will.
def user_info(username, gender, email_id='' ):
if email_id:

---

info = "My name is " + username.title() + " and I am a new user, and
my email ID is " + email_id.title() + ". My gender is " + gender.title() + "."
else:
info = "My name is " + username.title() + " and my gender is " +
gender.title() + "."
return info.title()
newuser = user_info('Dora', 'female')
print(newuser)
newuser1 = user_info('John', '[e-mail]', 'male')
print(newuser1)
newuser2 = user_info('Jimmy', '[e-mail]', 'male')
print(newuser2)
= RESTART: C:/Users/saifia computers/Desktop/sample.py
My Name Is Dora And My Gender Is Female.
My Name Is John And I Am A New User, And My Email Id Is Male. My
Gender Is [e-mail].
My Name Is Jimmy And I Am A New User, And My Email Id Is Male. My
Gender Is [e-mail].
