Exercise 2

Problem:

if num < 3
    print('The number is ' + num)
    print(f'{num is less than three')
        prin('thanks for playing!")

Solution:

1. SyntaxError: invalid syntax

   Missing : after if num < 3.

2. IndentationError: unexpected indent

   prin('thanks for playing!") is one space too far to the right.

3. SyntaxError: EOL while scanning string literal

   Mismatched quotes in prin('thanks for playing!"). String starts with a single quote and ends with a double

4. SyntaxError: f-string: expecting '}'

   The f-string in the line: print(f'{num is less than three') is missing a closing curly bracket after the variable num

5. NameError: name 'num' is not defined

   There is no value set for num. Define num and assign a number to it that will satisfy the condition in the if statment

6. TypeError: can only concatenate str (not "int") to str

   The value of num is an integer, which cannot be concatenated to a string. We need to convert num to a string using the str() function or by converting the string to an f-string.

7. NameError: name 'prin' is not defined

   A 't' is missing from the end of print(), preventing the function from being found.

Final code:

num = 1
if num < 3:
    # using an f-string
    print(f'The number is {num}')

    # using str()
    # print('The number is ' + str(num))

    print(f'{num} is less than three')

    print('thanks for playing!')

Final output:

The number is 1
1 is less than three
thanks for playing!
