Intro to Python Unit 6: Test Review

Front

Which of the following defines a global variable, range function, and for loop? Options: a. A global variable is a variable that is accessible throughout the entire program. The range function generates a sequence of numbers. A for loop is used to iterate over a sequence. b. A global variable is a variable that is only accessible within a function. The range function generates a random number. A for loop is used to execute a block of code once. c. A global variable is a variable that is accessible only within a class. The range function generates a list of strings. A for loop is used to define a function. d. A global variable is a variable that is accessible only within a module. The range function generates a sequence of characters. A for loop is used to terminate a program.
