Block coding is the basic form of computers programming and a great way to start learning coding.
Block based coding consists of easy to use block based interface. With block code one can learn the
programming logic and design better.
Text-based coding involves writing lines of code. It should be introduced when one got used to block
based coding. It is essentially typing instructions in a programming language with a syntax.
Syntax is the set of rules for writing a programming language. It is like the spelling and grammar of
the language that define its structure.
We have to follow the syntax carefully while writing the textual code. Let us understand it in AI
Connect.
Basics of Textual Coding
To start with the textual coding, you should have a clear understanding of the following coding
concepts:
Print Command
The print unction prints the specified message to the screen or other standard output de ice.
Also, the print command can be used to provide the information anywhere in the code.
It is very useful to know the status of your code.
Syntax: print(message/value)
For example,
print(‘I Love Coding’)
Usage: To print the output.
Block Code
Textual code
Notes
To print the value of a variable, we do not need to add it in double quotes. Whereas,
to print a message on the screen, we need to enclose them in double quotes.
