Question

Given the following statement:
import matplotlib.pyplot as plt 
'plt' in the above statement is .............. name.

• A. key
• B. alias
• C. variable
• D. function

Hint:

The \texttt{as} keyword in Python is used to define an alias for imported modules. This helps shorten module names for ease of use.

Answer 1

The Correct Option is B

Step 1: Understanding the import statement.
Python's \texttt{import} statement is used to incorporate libraries or modules into a script. An alias can be assigned to a module using \texttt{as} during import, simplifying repeated references to the full module name.
Step 2: Evaluate each option.
- Option (A) Key: A key in Python typically refers to dictionary keys and is irrelevant here. - Option (B) Alias: \texttt{plt} serves as the alias for the \texttt{matplotlib.pyplot} module, making this the correct choice. - Option (C) Variable: A variable stores a value or object, which is not the function of \texttt{plt} in this context. - Option (D) Function: Python functions are defined with \texttt{def}, which does not apply to \texttt{plt}.
Step 3: Conclusion.
In the given statement, \texttt{plt} is an alias for the \texttt{matplotlib.pyplot} module.
Final Answer: \[\boxed{\text{plt is an alias for the matplotlib.pyplot module.}}\]
