Step-by-Step Solution
Solution:
Step 1: Check function names and parameters
The correct function isplt.savefig(). plt.plot([1,2,3],[3,2,1]) plt.save('plot.png') plt.save('plot.svg') plt.save('plot.pdf') usesplt.save(), which is invalid.Step 2: Confirm saving with explicit format or extension
plt.plot([1,2,3],[3,2,1]) plt.savefig('plot') plt.savefig('plot') plt.savefig('plot') uses filenames without extensions, so format is unclear. plt.plot([1,2,3],[3,2,1]) plt.savefig('plot.png') plt.savefig('plot.svg') plt.savefig('plot.pdf') relies on extensions only, which works but may be less explicit.Step 3: Understand explicit format argument
plt.plot([1,2,3],[3,2,1]) plt.savefig('plot.png', format='png') plt.savefig('plot.svg', format='svg') plt.savefig('plot.pdf', format='pdf') uses both filename and explicitformatargument, ensuring correct file type saving.Final Answer:
Saves the plot in PNG, SVG, and PDF formats using explicit format arguments. -> Option CQuick Check:
Use plt.savefig(filename, format='ext') for clarity [OK]
Quick Trick: Use plt.savefig with filename and format='ext' for multiple saves [OK]
Common Mistakes:
- Using plt.save() instead of plt.savefig()
- Saving without file extensions causing format errors
- Not specifying format when filename lacks extension
