Certainly! Below is a Python program that meets all your specified requirements. You can run this code on PythonAnywhere or any Python environment.
```python
# Assign a value to a variable
# type: int
age = 25
# Print text and a variable
print("Your age is:", age)
# Get a decimal number from the user
# type: float
decimal_number = float(input("Please enter a decimal number: "))
# Perform a mathematical calculation on a variable
# Here, we will square the decimal number
# type: float (result of the calculation)
squared_number = decimal_number ** 2
# Demonstrate the use of a comma and a plus sign in a print statement
# Using a comma in one statement
print("The squared number is:", squared_number)
# Using a plus sign in another statement
print("The squared number is: " + str(squared_number)) # converting the float to string for concatenation
# Summary of variables
print("Variable types: age -> int, decimal_number -> float, squared_number -> float")
```
### Explanation of the Code:
1. **Variable Assignment**: The variable `age` is assigned an integer value of 25.
2. **Print Statement**: The program prints both text and the `age` variable using a comma, so it automatically separates them with a space.
3. **User Input**: It prompts the user to enter a decimal number, which is converted from a string to a float.
4. **Mathematical Calculation**: It computes the square of the entered decimal number.
5. **Comma and Plus Sign Demonstration**: It shows how to print outputs using both a comma (for `squared_number`) and a plus sign (for string concatenation).
6. **Comments**: The comments explain the data types of each variable throughout the code.
To run this code on PythonAnywhere, simply create a new file within the Console or Files tab, copy and paste the code, and execute it.
```python
# Assign a value to a variable
# type: int
age = 25
# Print text and a variable
print("Your age is:", age)
# Get a decimal number from the user
# type: float
decimal_number = float(input("Please enter a decimal number: "))
# Perform a mathematical calculation on a variable

# type: float (result of the calculation)
squared_number = decimal_number ** 2

Certainly! Below is the exact text you can copy and paste into the Python editor on PythonAnywhere. Simply follow these steps:
1. Log in to your PythonAnywhere account.
2. Go to the **"Files"** tab and create a new Python file (e.g., `my_program.py`).
3. Open the file and paste the following code exactly as it is:
```python
# Assign a value to a variable
# type: int
age = 25
# Print text and a variable
print("Your age is:", age)
# Get a decimal number from the user
# type: float
decimal_number = float(input("Please enter a decimal number: "))
# Perform a mathematical calculation on a variable
# Here, we will square the decimal number
# type: float (result of the calculation)
squared_number = decimal_number ** 2
# Demonstrate the use of a comma and a plus sign in a print statement
# Using a comma in one statement
print("The squared number is:", squared_number)
# Using a plus sign in another statement
print("The squared number is: " + str(squared_number)) # converting the float to string for concatenation
# Summary of variables
print("Variable types: age -> int, decimal_number -> float, squared_number -> float")
```
4. Save the file.
5. Go to the **"Consoles"** tab, start a new Python 3 console, and run your program by typing `exec(open('my_program.py').read())` or directly by navigating to the file and clicking "Run".
That's it! You should see the program execute and prompt you for input. Enjoy!
