Output of tool library list command

What is the output of the following command that lists all tools in the CNC tool library?

CNC Programming

list_tools()

A Error: Command not found

B [{'ToolID': 1, 'Type': 'Drill', 'Diameter': 10}, {'ToolID': 2, 'Type': 'End Mill', 'Diameter': 6}]

C []

D [{'ToolID': 1, 'Type': 'Lathe', 'Diameter': 12}]

💡 Hint

Think about what a tool library list command should return if tools are registered.

The command list_tools() returns a list of all tools currently registered in the tool library with their properties.

📝 Syntax

Correct syntax to add a tool to the library

Which of the following commands correctly adds a new drill tool with diameter 8 to the tool library?

A add_tool(type='Drill', 8)

B add_tool('Drill', diameter=8)

C add_tool(type='Drill', diameter=8)

D add_tool(diameter=8, 'Drill')

💡 Hint

Check the correct use of named parameters in the function call.

The function requires named parameters for type and diameter. Option C uses correct syntax.

Identify the error in tool removal script

What error will this script produce when trying to remove a tool by ID from the library? remove_tool(5) print('Tool removed')

CNC Programming

remove_tool(5)
print('Tool removed')

A KeyError: Tool ID 5 not found

B SyntaxError: missing parentheses

C TypeError: remove_tool() missing required argument

D No error, tool removed successfully

💡 Hint

Consider what happens if the tool ID does not exist in the library.

If tool ID 5 does not exist, the function raises a KeyError indicating the tool was not found.

Result of updating tool diameter

After running this script to update the diameter of tool ID 2 to 7, what is the diameter of tool ID 2?

CNC Programming

update_tool(2, diameter=7)
result = get_tool(2)['Diameter']
print(result)

A None

B 6

C Error: Tool ID not found

D 7

💡 Hint

The update_tool function changes the tool's properties if the ID exists.

The diameter is updated to 7, so get_tool returns the updated diameter.

Number of tools after batch import

If the tool library initially has 3 tools and you run a batch import script that adds 4 new tools but removes 2 existing tools, how many tools are in the library after the script?

A 5

B 7

C 4

D 3

💡 Hint

Add the new tools and subtract the removed tools from the initial count.

Starting with 3, adding 4 makes 7, removing 2 leaves 5 tools.
