The Program

This week's participation targets program comprehension. Review the given program below. Do not run the program.

word = "FUN"

def func1(word):
	starts_with = "f"
	
	if type(word) != str:
		return False
	
	if word[0].lower() == starts_with:
		return True
	print(f"{word} doesn't start with \"{starts_with}\"!")
	return False
	
print(func1("INFO1110"))
#Injection for Checkpoint 2 - print(starts_with)

Checkpoint 1 - Function Basics

1. How many parameters does function func1 have?
2. What is the output of this program? Defend your answer by tracing the lines in the program that were executed. Please complete the table with the following information:
   -Line : the line number in the program that was executed
   -Evaluation result : The outcome (e.g. value assignment, boolean expression evaluation result) of executing the respective line

Checkpoint 2 - Function scope

Predict the behaviour of the program if the statement print(starts_with) is injected into Line 15 of the program. Why?
