英文:
Polars / Python Limits Number of Printed Table Output Rows
问题
I understand your request. Here's the translated content:
有人知道为什么 Polars（或者可能是我的 PyCharm 设置或 Python 调试器）限制了输出中的行数吗？这让我很烦恼。
这是我正在运行的 Polars 代码，但我怀疑它与 Polars 无关，因为在谷歌上几乎找不到相关信息（而 ChatGPT 说它的信息太旧了哈哈）。
import polars as pldf = pl.scan_parquet('/path/to/file.parquet')result_df = (df.filter(pl.col("condition_category") == 'unknown').groupby("type").agg([pl.col("type").count().alias("counts"),])).collect()print(result_df)
英文:
Does anyone know why polars (or maybe my pycharm setup or python debugger) limits the number of rows in the output? This drives me nuts.
Here is the polars code i am running but I do suspect its not polars specific as there isnt much out there on google (and chatgpt said its info is too old haha).
import polars as pldf = pl.scan_parquet('/path/to/file.parquet')result_df =(df.filter(pl.col("condition_category") == 'unknown').groupby("type").agg([pl.col("type").count().alias("counts"),])).collect()print(result_df)

with pl.Config() as cfg:
cfg.set_tbl_rows(1000)
print(result_df)
or throw this at the top of your script if you prefer to not manage contexts.
import polars as pl
Configure Polars
