Is there way to round without converting to string then decimal: df = pd.DataFrame([(.21, .3212), (.01, .61237), (.66123, .03), (.21, .18),(pd.NA, .18)], columns=['dogs', 'cats']) df dogs cats 0 0.21 0.32120 1 0.01 0.61237 2 0.66123 0.03000 3 0.21 0.18000 4 <NA> 0.18000 Here is what I wanted to do, but it is erroring: df['dogs'] = df['dogs'].round(2) TypeError: float() argument must be a string or a number, not 'NAType' Here is another way I tried but this silently fails and no conversion occurs: tn.round({'dogs': 1}) dogs cats 0 0.21 0.32120 1 0.01 0.61237 2 0.66123 0.03000 3 0.21 0.18000 4 <NA> 0.18000 A: <code> import pandas as pd df = pd.DataFrame([(.21, .3212), (.01, .61237), (.66123, .03), (.21, .18),(pd.NA, .18)], columns=['dogs', 'cats']) </code> df = ... # put solution in this variable BEGIN SOLUTION <code> ## What to do - Edit `solution/solution.py` so the code passes the DS-1000 tests. - Do not access the internet or install new packages; required libraries are preinstalled in the Docker image. - Run tests locally via `bash tests/test.sh`. ## Notes - Keep the variable names/signatures implied by the prompt/code_context. - The evaluator uses the original DS-1000 `code_context` (`test_execution` / `test_string`). ``` --- Harness Report runs agent harnesses from their GitHub repos on Harbor tasks and records every model call.
