+
+In this workshop, you will practice how to use booleans and conditional statements in Python by building a movie ticket booking calculator.
+
+Begin by declaring variables that store information about the user and the movie show.
+
+As you learned in previous lessons, variables are assigned using the assignment operator (`=`) this way:
+
+```py
+# Assigns the value 10 to variable x
+x = 10
+```
+
+Create a variable named `base_price` to store the base price of the movie ticket and set its value to `15`. Create another variable named `age` to store the user's age and set its value to `21`.
+
+# --hints--
+
+You should declare a variable named `base_price`.
+
+```js
+({ test: () => (runPython(`assert _Node(_code).has_variable("base_price")`)) })
+```
+
+You should assign the integer value `15` to `base_price`.
+
+```js
+({ test: () => (runPython(`
+assert _Node(_code).find_variable("base_price").is_equivalent("base_price = 15")
+`)) })
+```
+
+You should declare a variable named `age`.
+
+```js
+({ test: () => (runPython(`assert _Node(_code).has_variable("age")`)) })
+```
+
+You should assign the integer value `21` to `age`.
+
+```js
+({ test: () => (runPython(`
+assert _Node(_code).find_variable("age").is_equivalent("age = 21")
+`)) })

+
+Now you need to store some string values about the movie ticket. You can store strings in Python this way:
+
+```py
+name = 'Alice'
+```
+
+Create a variable named `seat_type` to store the type of seat the user has selected and set its value to the string `Gold`. Create another variable named `show_time` to store the show time of the movie and set its value to the string `Evening`.
+
+Remember to surround both values with either single or double quotes.
+
+# --hints--
+
+You should declare a variable named `seat_type`.
+
+```js

+
+As you learned in previous lessons, in Python, an `if` statement can be used to run code depending on if a condition is true.
+
+An `if` statement consists of the `if` keyword, followed by a condition and a colon. The code to run when the condition is true, which must be indented, is called the body of the `if` statement.
+
+```py
+if condition:
+    # Code to execute if condition is True
+```
+
+In this step, you will check if the user is eligible to book a movie ticket based on their age.
+
+Create an `if` statement to check if `age` is greater than `17`. Inside the body of the `if` statement, print `User is eligible to book a ticket`. This will print the message only when the user's age is greater than `17`.
+
+Remember to indent the body of the `if` statement and surround the message with single or double quotes inside the `print()` call.
+
+# --hints--
+
+You should have an `if` statement.
+
+```js
+({ test: () => (runPython(`assert _Node(_code).find_ifs()[0]`)) })
+```
+
+The `if` statement condition should be `age > 17`.
+
+```js 
+({ test: () => (runPython(`
+_cond = _Node(_code).find_ifs()[0].find_conditions()[0] 
+assert _cond.is_equivalent("age > 17") or _cond.is_equivalent("17 < age")
+`)) })
+```
+
+You should have a `print()` call inside your `if` statement. Remember to indent the body of the `if` statement.
+
+```js
+({ test: () => (runPython(`
+assert _Node(_code).find_ifs()[0].find_bodies()[0].find_calls("print")[0]
+`)) })
+```
+
+You should print `User is eligible to book a ticket` inside your `if` statement. Remember to surround the message with single or double quotes.

+
+In Python, an `if` statement can also be placed inside the body of another `if` statement. This is called a nested `if` statement.
+
+A nested `if` statement allows you to check an additional condition only after the first condition has already been satisfied. The inner `if` statement will run only if the outer `if` condition is true.
+
+```py
+if condition1:
+    # Code to execute if condition1 is True

+Now you will calculate service charges based on the type of seat the user has selected.

+There is one more exception to the booking rules. Users between `18` and `21` can book evening shows if they are members.

+When multiple logical operators are used in an `if` statement, conditions joined with `and` are evaluated before conditions joined with `or`. Parentheses `()` are used in Python to group conditions and control the order in which they are evaluated.

+
+Now, add an `else` clause to your `if` statement and update the `service_charges` value to `1` inside the `else` body.
+
+# --hints--
+
+Your new `if` statement should have an `else` clause.
+
+```js
+({ test: () => (runPython(`
+assert _Node(_code).find_ifs()[4].find_ifs()[0].find_conditions()[1].is_empty() 
+`)) })
+```
+
+You should assign the integer value `1` to `service_charges` variable inside your `else` clause.
+
+```js
+({ test: () => (runPython(`
+_var = _Node(_code).find_ifs()[4].find_ifs()[0].find_bodies()[1].find_variable("service_charges")
