Python Basics: Variables, Functions, and More

How many lines of code need to be changed to make the calculate function return the product instead of the sum?

What output is produced by the function print_water_temp_for_coffee when called with a temperature of 205?

What will be the output of printing calc(4, 5) and calc(1, 2)?

What are exceptions designed to handle in a program?

Which of the following is NOT a keyword related to exception handling in Python?

Which symbol in Python is used to create a comment?

What is the resulting value of the expression: 1 + int(3.5) / 2?

What is the data type used for floating point numbers in Python?

What does the expression 'key != 'q'' evaluate to when a user types 'q'?

Which of the following correctly removes the value 'Google' from a set named companies?

If grade is assigned the value 75, which letter will be output based on the given logic block?

What is the term for a word that is part of the Python language and cannot be used as a variable name?

What is the value of x after executing the statement 'x = -2'?

Variables and Comments

Variables are symbols representing data
The symbol '#' is used for comments in Python
int() converts strings to integers

Errors and Functions

Dividing by zero is a runtime error
IDEs are used for program development including source code writing
int() converts strings to integers

Data Types

float is the data type for floating-point numbers
-2 is the result of x after the code provided.
keyword can't be used as a variable name in Python

Print Statements

print('I won\'t quit!') displays the literal string I won't quit!
print(f'{"Tokyo":s} had {9.273000:f} million people in {2015:d}') displays Tokyo had 9.273000 million people in 2015

Set Operations

companies.remove('Google') removes 'Google' from the companies set.

Lists and Operations

names_list + digits_list concatenates the two lists.
The result of names_list is ['one', 'two', 'three', '1', '2', '3']

String Indexing

text_line[6] extracts the character at index 6 from the string text_line.
The result is 'S'.

Conditional Logic

Logic to determine a user's input for continuing or quitting (key != 'q')

Conditional Statements

Statements for determining the Output given different x values
-x values from 21 to 40 correspond to "Medium" output

Conditional Output

A grade of 75 results in "C" being printed (as per the given conditional logic)

Operator Precedence

The multiplication (*) operation is evaluated before addition (+) and subtraction (-) in the expression x + y < y - z * 2
Looping and values- Loops can work with negative values as well.

Looping

Iteration describes each cycle of a loop
Infinite loops are generally not desirable and are not favorable

Function Execution and Return

After a function's last statement, the program returns to the line following the function call
calc_square_area(val) returns the calculated area value

Exceptions

Exceptions handle errors in programs
EOFError, ZeroDivisionError, and ValueError are examples of common exceptions in Python
The programmer is able to define their own exception types.

This quiz covers fundamental concepts of Python programming, including variables, comments, data types, and print statements. Test your knowledge on how to handle errors, set operations, and list manipulations within Python. Perfect for beginners looking to solidify their understanding of the basics.
