Beginning Python (Video 26)

This video tutorial covers the creation of two small programs using loops and conditionals. The first program sums even numbers from a list, while the second extracts consonants from a string. The tutorial provides step-by-step guidance on using for loops, if statements, and string manipulation techniques. It concludes with a brief overview of what to expect in the next video.

What are the two small programs discussed in the lesson designed to do?

• Sum all numbers in a list and extract vowels from a string

• Divide numbers in a list and extract special characters from a string

• Sum even numbers from a list and extract consonants from a string

• Multiply all numbers in a list and extract digits from a string

What is the initial value of the variable used to keep track of the total in the first program?

• One

• Zero

• The first number in the list

• The last number in the list

Which operation is used to check if a number is even in the first program?

• Division

• Subtraction

• Addition

• Modulo

What is the purpose of the shorthand 'total += N' in the first program?

• To multiply the total by N

• To subtract N from the total

• To add N to the total

• To divide the total by N

In the second program, which characters are ignored when extracting consonants from a string?

• Spaces and exclamation marks

• Vowels and numbers

• Digits and punctuation

• Uppercase letters

What data structure is used to store the consonants found in the second program?

• A set

• A list

• A tuple

• A dictionary

What is the next step after extracting consonants in the second program?

• Convert the list to a dictionary

• Sort the consonants alphabetically

• Print each consonant separately

• Convert the list back into a string
