Answer 1

Here's a simple Python program that meets all the specified requirements. The program assigns a value to a variable, prints a message along with the variable, collects a decimal number from the user, performs a calculation, and demonstrates the use of both a comma and a plus sign in print statements.

# Assigning a value to a variable
integer_variable = 5  # This is an integer

# Printing text and the variable
print("The value of the integer variable is:", integer_variable)

# Getting a decimal number from the user
decimal_variable = float(input("Please enter a decimal number: "))  # This will store a float

# Performing a mathematical calculation on a variable
result = integer_variable * decimal_variable  # Performing multiplication

# Demonstrating the use of a comma in the print statement
print("The result of multiplying", integer_variable, "and", decimal_variable, "is:")

# Demonstrating the use of a plus sign in a print statement
print("The result is: " + str(result))  # Converting result to string to concatenate

Explanation of the program:

1. Variable Assignment: integer_variable is assigned an integer value of 5.
2. Print with Variable: It prints a message along with the value of integer_variable.
3. User Input: It prompts the user to enter a decimal number and converts the input to a float.
4. Mathematical Calculation: It multiplies the integer_variable by the user-input decimal and stores the result in result.
5. Print Statements:
   • The first print statement uses commas to print multiple items.
   • The second print statement uses a plus sign to concatenate a string with the string representation of the result.

Data Types:

• integer_variable is of type int.
• decimal_variable is of type float.
• result is also of type float as it is the product of an int and a float.
