NettetBecause NaN is a float, a column of integers with even one missing values is cast to floating-point dtype (see Support for integer NA for more). pandas provides a nullable integer array, which can be used by explicitly requesting the dtype: In [14]: pd.Series( [1, 2, np.nan, 4], dtype=pd.Int64Dtype()) Out [14]: 0 1 1 2 2 3 4 dtype: Int64
NettetDepending on whether na_values is passed in, the behavior is as follows: If keep_default_na is True, and na_values are specified, na_values is appended to the default NaN values used for parsing. If keep_default_na is True, and na_values are not specified, only the default NaN values are used for parsing. jellycat huggady dino largeNettet8. sep. 2016 · When I load data I get my integer column converted to float64, specifying dtypes will raise exception on NAs in integer. ... read_csv falsely detect NA in integer … jellycat huge bunnyNettetAssuming that you have a dataset with columns N1 (numeric), N2 (numeric) and S (string) , here are a few example formulas: 2 + 2 N1 + N2 min (N1, N2) # Returns the smallest of N1 and N2 replace (S, 'old', 'new') # Returns the value of S with ‘old’ replaced by ‘new’ if (N1 > N2, 'big', 'small') # Returns big if N1 > N2, small otherwise Note jellycat huge bashful bunnyNettetThe special value NaN (Not-A-Number) is used everywhere as the NA value, and there are API functions DataFrame.isna () and DataFrame.notna () which can be used across the dtypes to detect NA values.
