Use.fillna()to replace the NaN values with integer value zero. For Exampledf['Fee']=df['Fee'].fillna(0).astype(int)method. # Convert "Fee" from float to int and replace NaN valuesdf['Fee']=df['Fee'].fillna(0).astype(int)print(df)print(df.dtypes) ...
Now by using the same approaches usingastype()let’sconvert the float column to int (integer) type in pandasDataFrame. Note that while converting a float to int, it doesn’t do any rounding and flooring and it just truncates the fraction values (anything after). The below example converts...
from pyspark.sql.types import IntegerTypedf = df.withColumn('order id', func.col('order id').cast(IntegerType())) 围棋类型转换与类型转换 在下面的代码中,常量的乘法在编译时完成,然后将结果转换为float,并作为float64存储在f中。运行时没有类型转换。 var f float64 = i * c 以下是无效的Go代码...
