Learning Python: The Ultimate Guide for Beginners to Coding with Python with Useful Tools

Simple if Statements

---

In  any  programming  language,  the  “if  statement”  is  the  simplest  to  come
across. It only requires a test or condition with a single action following it,
respectively. The syntax for this statement is as follows:
if condition:
perform action
The  first  line  can  contain  any  conditional  statement  with  the  second
following  the  action  to  take.  Ensure  to  indent  the  second  line  for  clarity
purposes.  If  the  conditional  statement  is  true,  then  the  code  under  the
condition is executed. However, if it is false, the code is ignored.
For instance, we have set a standard that the minimum score for a person to
qualify  for  a  football  match  is  20.  We  want  to  test  if  such  a  person  is
qualified to participate.
person  =21
if person >= 20
print(“You are qualified for the football match against Valencia.”)
In the first line, we define the person’s age to 21 in order to qualify. Then
the second line evaluates if the person is greater than or equal to 20. Python
then executes the statement below because it fulfills the condition that the
person is above 20.
You are qualified for the football match against Valencia.
Indentation is very significant when using the “if statement” like we did in
the “for loop” situations. All indented lines are executed once the condition
is  satisfied  after  the  if  statement.  However,  if  the  statement  returns  false,
then the whole code under it is ignored, and the program halted.
We can also include more code inside the if statements to display what we
want. Let us add another line to display that the match is between Chelsea
and Valencia at the Standford Bridge.
person  =21

if person >= 20
print(“You are qualified for the football match against Valencia.”)
print(“The match is between Arsenal and Valencia.”)
Print(“The Venue is at the Emirate Stadium in England.”)
The  conditional  statement  passes  through  the  condition  and  prints  the
indented  actions  once  the  condition  is  satisfied.  The  output  will  be  as
follow:
You are qualified for the football match against Valencia.
The match is between Arsenal and Valencia.
The Venue is at the Emirate Stadium in England.
Assuming  the  age  is  less  than  20,  and  then  there  won’t  be  any  output  for
this  program.  let  us  try  another  example  before  going  into  another
conditional statement.
name = “Abraham Lincoln”
if name = “Abraham Lincoln”
print(“Abraham Lincoln was a great United State President.”)
print(“He is an icon that many presidents try to emulate in the world.”)
The output will be:
Abraham Lincoln was a great United State President.
He is an icon that many presidents try to emulate in the world.
