Question

PLEASE DO THIS IN PYTHON!!

1.) Goal: Become familiar with The Python Interpreter and IDLE.

Use IDLE to type, compile, and run (execute) the following programs.

Name and save each program using the class name. Save all programs in one folder, call it Lab1-Practices.

Save all programs for future reference as they illustrate some programming features and syntax that you may use in other labs and assignments.

================================== Program CountDown.py ===================================

# Program CountDown.py

# Demonstrate how to print to console/screen.

# Prints two lines of output representing a rocket countdown.

   

print ("Three...", end =" ")# end = “ “ prevents print from creating a new line

print ("Two...", end =" ") # end = “ “ prevents print from creating a new line

print ("One...", end =" ") # end = “ “ prevents print from creating a new line

print ("Zero...", end =" ") # end = “ “ prevents print from creating a new line

print ("Liftoff!")

print ("Houston, we have a problem.")

================================== Program Addition.py ====================================

# Program Addition.py

# Demonstrate the difference between the addition and string concatenation operators.

# Concatenates and adds two numbers and prints the results.
      
print ("24 and 45 concatenated: ", 24, 45)
print ("24 and 45 added: ", (24 + 45))

==================================== Program Echo.py ======================================

# Program Echo.py

# Demonstrate reading a string from the user.

# Reads a character string from the user and prints it.

message = input("Enter a line of text: ")

print ('You entered: /', message, '/')

=================================== Program GasMileage.py =================================

# Program GasMileage.py

# Calculates fuel efficiency based on values entered by the user.   

miles = int(input ("Enter the number of miles: ") )

gallons = int(input("Enter the gallons of fuel used: ") )

mpg = miles / gallons

print ("Miles Per Gallon: ", mpg)

==================================== Program Facts.py =====================================

# Program Facts.py

# Demonstrate string concatenation operator conversion of an integer to a string.

# Prints various facts.

   

# Strings can be concatenated into one long string

print ("We present the following facts for your ", " extracurricular edification:")       

     

# A string can contain numeric digits

print ("Letters in the Hawaiian alphabet: 12")      

     

# A numeric value can be concatenated to a string

print ("Dialing code for Antarctica: ", 672)

print ("Year in which Leonardo da Vinci invented ", "the parachute: ", 1515)

print ("Speed of ketchup: ", 40 ," km per year")
