pandas.Index.astype¶
- 
Index.astype(dtype, copy=True)[source]¶
- Create an Index with values cast to dtypes. The class of a new Index is determined by dtype. When conversion is impossible, a ValueError exception is raised. - Parameters: - dtype : numpy dtype or pandas type - copy : bool, default True - By default, astype always returns a newly allocated object. If copy is set to False and internal requirements on dtype are satisfied, the original data is used to create a new Index or the original Index is returned. - New in version 0.19.0.
