Intro to Programming
What is programming?
Programming is a set of instructions to complete a task.
The components of computer programming;
Environment; is the editor where you are going to write the code.
Structure of the code;
Follow the concept of IPO (input-processing-output)
elements of a programming language
3) How to run the program
For the environment; we are going to use www.pythontutor.com or https://py3.codeskulptor.org/
Let us write a simple program that will add two numbers
# inputs
first_number = 5
second_number = 7
#process
sum = first_number + second_number
#output
Print (“Sum =”, sum)
The above code is not useful because the input values are hard coded, before we correct this, let us talk about the elements of any programming language.
Storage or variable; in the above example first_number and second_number are variables. Note that first_number is not the same as First_number. Python is a case sensitive language.
If – then
we can say if (sum > 10):
print(“Too much”)
3) loop
for - in
2
print("Welcome to programming")
# inputs
first_number = float(input("Enter first number "))
second_number = float(input("Enter second number "))
#process
sum = first_number + second_number
#if-then
if (sum > 10):
print("too much")
else:
#output
print ("Sum =", sum)
#loop
for i in range(int(sum)):
print(i)
