How do I use tracemalloc in Python?

Tracemalloc is a built-in module in Python for tracking memory allocations. You can start using it by importing the module and calling tracemalloc.start(). Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

import tracemalloc

tracemalloc.start()

# Your code here

snapshot = tracemalloc.take_snapshot()
for stat in snapshot.statistics('lineno'):
    print(stat)

This will show you memory usage statistics by line number.

How can I filter the statistics to show only specific files?

You can filter the statistics by using the filter_tracemalloc method. For example:

filtered_stats = snapshot.statistics('lineno')
filtered_stats = [s for s in filtered_stats if 'your_file.py' in s.traceback]

This will give you statistics only for 'your_file.py'.
