Conditions in Python Lesson 4:
In the English language the word conditions: means. And we use the terms in programming languages to determine the way to work on the program and the conditions are considered one of the most important tools for programming languages in general, so imagine that there is a programming language without the conditions, how will you create an integrated program, and from its name, it executes an order if a specific event has occurred or did not happen.
Of course, there are several ways to set the condition or different conditions, and we will now, as we are accustomed to explaining the conditions in Python, in the initial form, and then include in future lessons to study almost all cases and methods of implementing and writing conditions
We will now explain the condition statements in Python
The following structure explains the Syntax method:
- (condition) if condition
In this line, we have set a condition so that if this condition is true then implement the code
- (condition) elif condition
Also in this line, we have set a condition so that if this condition is true then implement the code
- (condition) else
In this line, we have set a condition so that if any of the previously set conditions are not met, then implement this code instead
Note that it is not necessary to put the three previous sentences and put them in the previous example completely inside each program, but only to use the condition is required to use the condition statement (if)
Example:
Var = happy
Var = sad
If (happy == True):
Print ("smile")
Elif (sad == True):
Print ("be happy")
Else:
Print ("I dunno what I say")
Note: The Tab must be indented so that the program knows that the instructions are related to the conditional statement.
Explanation of condition statements in the Python programming language
Word (sentence) condition (if)
This word in itself is translated into Arabic (if), and it is used in the event that you want to implement a code (command) according to a specific condition that you put in place just like normal life behavior.
Word (sentence) condition (else)
This word in itself is translated into Arabic (something else).
And it is used only if you want to execute a specific code (command) in case all the conditions before it was not met, or in other words (false).
Taking into account that it must always be placed in the last conditional sentences within the program structure, as it is resorted to only in the event that no conditional sentence written before it is executed.
(Elif) (else if) (elif)
