You want to ensure SciPy is installed and ready to use in a new Python project. Which sequence of commands is best to install SciPy and verify its version in one script?
A<code>pip install scipy import scipy print(scipy.__version__)</code>
B<code>import scipy pip install scipy print(scipy.__version__)</code>
C<code>import scipy print(scipy.__version__)</code>
D<code>!pip install scipy import scipy print(scipy.__version__)</code>
Step-by-Step Solution
Solution:

  1. Step 1: Understand installation and verification in scripts

    Directly running pip install inside a script requires shell command syntax like !pip install in notebooks.

  2. Step 2: Identify the correct order and syntax

    First install SciPy with !pip install scipy, then import and print version to verify.

  3. Final Answer:

    !pip install scipy import scipy print(scipy.__version__) -> Option D

  4. Quick Check:

    Use '!pip install' in scripts before import to install [OK]
Quick Trick: Use '!pip install scipy' in scripts before import to install [OK]
Common Mistakes:
MISTAKES
  • Trying to run 'pip install' as Python code without '!'
  • Importing SciPy before installing it
  • Assuming pip install works inside Python without shell command
