Consider the following function definition:

def do$\_$something$($number$)$:

return number $*2$

Given the function definition, what will the following statement display? print$($do$\_$something$(10))$

a$.0$

b$.2$

c$.10$

d$.20$

The three steps that must be taken by a program when it uses a file are to $$ the file.

a$.$ open, process, and close

b$.$ read, execute, and write

c$.$ process, test, and close

d$.$ read, write, and report

When you work with $a(n)q,$ file, you access data from the beginning of the file to the end of the file.

a$.$ sequential access

b$.$ direct access

c$.$ read$-$only

d$.$ write$-$only

If you want to write data to a file but do not want to erase the existing contents, open the file in $q,$ mode.

a$.$ append

b$.$ write

c$.$ safe

d$.$ add

The readline method returns $a(n)q,$ when it has attempted to read beyond the end of a file.

a$.$ random string

b$.$ warning message

c$.$ error message

d$.$ empty string
