You will study pip and requirements. It belongs to the Real-World Tools phase.
Remember this:
requirements.txt captures dependency versions for reproducibility.
Practice step by step. Do not rush. Each run should show you something new.
Tip:
Pin versions in production projects.
Avoid this:
Forgetting to update requirements file.
Your challenge:
Export requirements and recreate environment.
Go to the challenge lab below. Fix errors until the output looks right. Then press the green button to complete the topic.
Example code
Copy this example if it helps. Change it so it matches pip and requirements.
# Topic: pip and requirements
def main():
sample = "edit me"
# TODO: apply pip and requirements concept here
result = sample
print("Result:", result)
if __name__ == "__main__":
main()
Challenge
Export requirements and recreate environment.
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.
