沉默警告在熊貓

Question

在運行時：

mydf = pd.read_csv(p_file, sep=',', error_bad_lines=False, index_col=False) 

我得到許多線像下面這樣：

... 
Skipping line 77432: expected 15 fields, saw 16 
Skipping line 77497: expected 15 fields, saw 16 
Skipping line 77528: expected 15 fields, saw 16 
Skipping line 77560: expected 15 fields, saw 16 
Skipping line 77625: expected 15 fields, saw 16 
Skipping line 77656: expected 15 fields, saw 16 
... 

我怎麼能沉默這些警告？我如何找到Pandas中的警告類列表？

Answer 1

看起來read_csv有warn_bad_lines kwarg，所以你應該能夠做到以下幾點：

mydf = pd.read_csv(p_file, sep=',', error_bad_lines=False, index_col=False, warn_bad_lines=False) 

http://pandas.pydata.org/pandas-docs/stable/generated/pandas.read_csv.html#pandas.read_csv

「如果error_bad_lines是假，而warn_bad_lines是真實的，警告每個「壞行」將被輸出（僅在C語法分析器中有效）。「
