Pandas Basics
DataFrame is table-like structure for analysis.
Inspect with head and info first.
Blindly transforming without checking nulls.

This lesson is about Pandas Basics. You are in the Real-World Tools part of the course.
Main idea:
DataFrame is table-like structure for analysis.
How to learn it: type a very small program first. Run it. Change one line and run again.
Tip:
Inspect with head and info first.
Common mistake:
Blindly transforming without checking nulls.
Your challenge:
Load CSV and show top 5 rows with one filter.
Scroll down to the challenge lab. Run your code there. When the output meets the task and the checks pass, press the green button to finish this topic.
Example code
Copy this example if it helps. Change it so it matches Pandas Basics.
# Topic: Pandas Basics
def main():
sample = "edit me"
# TODO: apply Pandas Basics concept here
result = sample
print("Result:", result)
if __name__ == "__main__":
main()
Challenge
Load CSV and show top 5 rows with one filter.
Before you can finish: your output should include at least 16 characters; at least 1 non-empty line(s); no crash traceback—fix errors until the program runs cleanly.
Use Run. Read the output. Change your code until the task is done.
