To convert a string column to an integer in a Pandas DataFrame, you can use theastype()method. To convert String to Int (Integer) from Pandas DataFrame or Series useSeries.astype(int)orpandas.to_numeric()functions. In this article, I will explain theastype()function, its syntax, parameters...
我在pandas 中有一个数据框,其中包含混合的 int 和 str 数据列。我想首先连接数据框中的列。为此,我必须将int列转换为str。我试图做如下: mtrx['X.3'] = mtrx.to_string(columns = ['X.3']) 要么 mtrx['X.3'] = mtrx['X.3'].astype(str) 但在这两种情况下它都不起作用,我收到一条错误消息...
