Hint: Use a for loop and a break statement.

Exercise 9: Loop Until Specific Input

Filename: e09_loop_until_input.py

Write a program to repeatedly ask for user input until the user types "quit".

Hint: Use a while loop and a break statement when the input is "quit".

Exercise 10: Skip Lowercase Letters

Filename: e10_skip_lowercase.py

Write a program to iterate through a string and print only the uppercase letters.

Hint: Use a for loop and a continue statement to skip lowercase letters.

Exercise 11: Stop on a Specific Value in a List

Filename: e11_stop_at_list_value.py

Write a program to iterate through a list of numbers and stop when you find the number 15.

Hint: Use a for loop and a break statement.

Exercise 12: Skip Empty Strings

Filename: e12_skip_empty_strings.py

Write a program to iterate over a list of strings and print only non-empty strings.

Hint: Use a for loop and a continue statement to skip empty strings.

Exercise 13: End Loop on User Condition

Filename: e13_end_on_condition.py

Write a program that keeps asking the user for numbers and prints them until the user enters a negative number.

Hint: Use a while loop and break when the input is negative.

Exercise 14: Skip Multiples of 5

Filename: e14_skip_multiples_of_5.py

Write a program to print numbers from 1 to 20, but skip all numbers that are multiples of 5.

Hint: Use a for loop and a continue statement to skip multiples of 5.

Exercise 15: Exit Loop on Specific Character

Filename: e15_exit_on_character.py

Write a program to iterate through the string "PythonProgramming" and stop when the character 'g' is found.

Hint: Use a for loop and a break statement.

Exercise 16: Count Only Non-Vowels

Filename: e16_count_non_vowels.py

Write a program to count and print the number of non-vowel characters in a given string.

Hint: Use a for loop and a continue statement to skip vowels.

Exercise 17: Break on Special Character

Filename: e17_break_on_special.py

Write a program that iterates over a string and stops when a special character (like '@', '!', etc.) is found.

Hint: Use a for loop and a break statement.

Exercise 18: Skip Zero in a List

Filename: e18_skip_zero.py

Write a program to iterate through a list of numbers and print all values except 0.

Hint: Use a for loop and a continue statement to skip zero.

Exercise 19: Exit on User Input

Filename: e19_exit_on_user_input.py

Write a program that asks for user input continuously until the user types "exit".

Hint: Use a while loop and a break statement when the input is "exit".

Exercise 20: Skip Characters in Range

Filename: e20_skip_characters.py

Write a program to print each character in a string, but skip characters from index 3 to 5.

Hint: Use a for loop and a continue statement with a conditional statement for the index.

Key Takeaways

These exercises will help you understand how to effectively use break and continue to control the flow of loops in Python. Practice each example, and understand how these control statements change the behavior of loops to gain mastery over conditional logic in your programs.
