Python Variables and Literals

🔹 Assignment Set: Python Variables & Literals (Beginner Level)

---

1) Simple Variable Assignment

Write Python code to do the following:

1. Create a variable called age and assign your age to it.

2. Create a variable called name and assign your name (as a string) to it.

3. Print both variables.

Example expected output (your values will vary):

25
Alice

---

2) Reassigning Variables

Create a variable city and assign it any city name (string). Then change the value of city to a different city and print it each time.

Expected pattern:

city = "Toronto"
print(city)

city = "Vancouver"
print(city)

---

3) Multiple Variable Assignment

In one line, assign values to three variables:

• x = 10

• y = 20

• z = 30

Then print all three variables.

---

4) Numeric Literals

Create these variables:

• integer_val = 100

• float_val = 15.5

• complex_val = 2 + 3j

Print each one.

---

5) String Literals

Create variables holding:

• A single-quoted string (e.g., 'Python')

• A double-quoted string (e.g., "Beginner")

Print both.

---

6) Boolean Literals

Create two variables:

• is_student = True

• has_pet = False

Print both variables and their types.

---

7) Special Literal: None

1. Create a variable result and assign None to it.

2. Use an if statement to check if result is None, and print a message like:

No value assigned!

---

8) Collection Literals

Create and print the following literals:

• A list of 3 numbers: [1, 2, 3]

• A tuple of 3 strings: ("a", "b", "c")

• A set of 3 values: {10, 20, 30}

• A dictionary with 2 key–value pairs: {"name": "Alice", "age": 25}

---

9) Binary, Octal & Hex Literals

Create variables:

• bin_val = 0b1010

• oct_val = 0o12

• hex_val = 0xA

Print them. (They should all print the number 10.)

---

10) Simple Expressions with Variables

Create two numeric variables a and b. Assign them values like 3 and 7, then:

• Print their sum

• Print their product

---

Here are 10 more very basic assignments on Python Variables & Literals. These stay strictly foundational.

---

11) Swap Two Variables

Create two variables:

a = 5
b = 10

Swap their values and print them.

Expected output:

10
5

---

12) Type Checking

Create variables:

x = 50
y = 50.0
z = "50"

Print the type of each variable using type().

---

13) String Concatenation

Create two string variables:

first_name = "John"
last_name = "Doe"

Combine them into one variable called full_name with a space in between. Print the result.

Expected:

John Doe

---

14) Length of a String

Create a variable:

language = "Python"

Print the number of characters in the string.

---

15) Convert Data Types

Create:

num_str = "100"

Convert it into an integer and print:

• The converted value

• Its type

---

16) Using Escape Characters

Create a string that prints:

Hello
World

Use \n inside a single string literal.

---

17) Boolean from Comparison

Create:

a = 10
b = 20

Store the result of a > b in a variable called result and print it.

---

18) Update a Variable

Create:

count = 0

Increase its value by 1 and print it.

Expected:

1

---

19) Check Variable Identity

Create two variables:

x = None
y = None

Use is operator to check if x and y refer to the same object. Print the result.

---

20) Create a Simple Profile Dictionary

Create a dictionary variable profile with keys:

• "name"

• "age"

• "city"

Print the dictionary.

Example structure:

{
    "name": "Alice",
    "age": 25,
    "city": "Toronto"
}
