Python Basics for Grade 7 Students

What is a variable in Python?

• A variable in Python is a type of snake.

• A variable in Python is a reserved memory location to store values.

• A variable in Python is a mathematical equation.

• A variable in Python is a type of function.

How do you declare a variable in Python?

• variable_name = value

• value = variable_name

• variable = value

• declare variable = value

What is the purpose of loops in Python?

• Loops in Python are designed to skip over code blocks

• The purpose of loops in Python is to print statements only once

• The purpose of loops in Python is to iterate over sequences or execute a block of code repeatedly.

• Loops in Python are used for sorting data

What are the different types of loops in Python?

• do loop

• for loop, while loop, nested loops

• until loop

• repeat loop

What is a function in Python?

• A function in Python is a block of reusable code that performs a specific task.

• A function in Python is a variable that stores data

• A function in Python is a loop that iterates over a list

• A function in Python is a keyword used to define classes

How do you define a function in Python?

• Using the 'func' keyword followed by the function name and parentheses containing parameters, then indenting the function body to contain the code to be executed.

• Using the 'function' keyword followed by the function name and parentheses containing parameters, then indenting the function body to contain the code to be executed.

• Using the 'define' keyword followed by the function name and parentheses containing parameters, then indenting the function body to contain the code to be executed.

• Using the 'def' keyword followed by the function name and parentheses containing parameters, then indenting the function body to contain the code to be executed.

What are conditional statements in Python?

• Conditional statements in Python are used for mathematical calculations only.

• Conditional statements in Python are used to define variables.

• Conditional statements in Python are used to repeat a block of code a specific number of times.

• Conditional statements in Python are used to perform different actions based on whether a certain condition is true or false.

Give an example of an if statement in Python.

• if x > 5: print('x is greater than 5')

• if x != 5: print('x is not equal to 5')

• if x == 5: print('x is equal to 5')

• if x < 5: print('x is less than 5')

What are data structures in Python?

• Data structures in Python are used for cooking recipes.

• Data structures in Python are ways of organizing and storing data to enable efficient access and modification.

• Data structures in Python are only used for text processing.

• Data structures in Python are designed to make data less accessible.

Explain the concept of file handling in Python.

• File handling in Python is only possible with external libraries, not built-in functions.

• File handling in Python is done using built-in functions like open(), read(), write(), and close(). These functions provide a way to work with files in different modes such as read mode, write mode, append mode, etc.

• File handling in Python is done using built-in functions like open(), read(), write(), and delete().

• File handling in Python is limited to text files only, not binary files.
