The range() function generates numbers starting from 0, and range(3) returns [0, 1, 2].

Correct Answer: len()

The len() function returns the number of elements in a list.

Correct Answer: Skips the current iteration and continues with the next one

The continue statement skips the remaining code in the current iteration and proceeds to the next iteration of the loop.

Correct Answer: if key in dict:

The in operator checks if a key exists in a dictionary.

Correct Answer: float()

The float() function converts a number into a floating-point number.

Correct Answer: global var_name

The global keyword is used to declare a global variable inside a function.

Correct Answer: Checks if a string starts with a specified value

The startswith() method returns True if the string starts with the specified prefix.
