[英]how to remove the rows which has non-numeric data in python
Amount column consists of texts金额栏由文本组成
I have a column which is supposed to be an integer which is saved as object in the DataFrame.我有一列应该是 integer,它在 DataFrame 中保存为 object。 I tried to remove the columns which are not numeric by using the below codes:我尝试使用以下代码删除非数字的列:
df[df.columns[8]] = df[df.columns[8]].apply(pd.to_numeric, errors='coerce').fillna(0).astype(float).astype(int).dropna()
But the code is not working.但是代码不起作用。 I tried to replace the texts with 0 but its not working.我试图用 0 替换文本,但它不起作用。
This will render string rows to NAs.这会将字符串行呈现给 NA。
df["Amount in USD"] = pd.to_numeric(df["Amount in USD"], errors='coerce')
Then just filter out rows which has NAs.然后只需过滤掉具有 NA 的行。
df = df[df["Amount in USD"].notnull()]
