Output

displays the result of a program or stores them in a file.

Languages like java php, and python ________

do not rely on compilers to run programs.

The range() function defaults to increment the sequence by 2, however it is possible to specify the increment value by adding a second parameter: range(30, 1)

false

a function is defined using the reserved word define

false

false

numbers can never be converted into strings

false

the output of the following statement is: "abcd"[2:]

false

the return value of a function cannot be assigned to a variable
