PYTHON TUTORIALS

Different Ways to Use the Print Function

Summary

• If you want to pass a basic message to the Terminal (a.k.a Console), use the following syntax:
  print("[message]")
• If you want to pass a message with multiple value, use the following syntax:
  print([value1], [value2], [value3])
• The default ending for a printed message is a new line. If you want to override this, use the end argument with the following syntax:
  print([value1], end="")
• NOTE: If the Terminal in VS Code doesn't open by default, simply press "CTRL + `" (tick mark to the left of the number 1 on your keyboard) to open it. This would be "CMD + `" on Mac.
• NOTE:If you want to clear your VS Code Terminal, simply type "clear".

How and Why to Use F-Strings

Summary:

• The F-String is used to easily combine raw strings with variables of different data types without needing to change data types. This is used with the following syntax:
  f'[string] {[variable_name]}'
• F-Strings are much easier to use than multi-string concatenation (as shown in the previous tutorial), as it allows you to combine multiple data types without type casting. Example:
  name = 'Melissa'
age = 35
experience = 2.5
f'Hello, my name is {name}! I am {age} years old and have {experience} years of coding experience.'

OUTPUT: "Hello, my name is Melissa! I am 35 years old and have 2.5 years of coding experience."
• F-Strings are commonly used in conjunction with the print function to print out dynamic strings. Example:
  name = 'Ian'
print(f'{name} has arrived at the station.')

Exercise

Congratulations! You just completed the Print Function Tutorial! To help test your knowledge, let's practice outputting some messages to the Terminal.
**It's highly recommended that you complete the exercise outlined in the previous tutorial before beginning this exercise.**

Instructions:

1. Open your IDE (e.g., VS Code, PyCharm, Spyder).
2. Create a New Python File. Name it "print-function.py"
3. In the Newly Created Python File, complete the following tasks:
1. Declare a variable named "company" and give it a value of 'XYZ Corporation'.
2. Declare a variabled named "stock_price" and give it a value of 14.50.
3. Declare a variable named "stock_exchange" and give it a value of 'NASDAQ'.
4. Print out the following message: "The Stock Exchange has Opened!"
5. Print out the following message: "The Buying and Selling Process will Begin NOW!"
6. Print out the following message: "[company]'s Stock Price is opening at $[stock_price] on the [stock_exchange]."
