By using PySpark withColumn() on a DataFrame, we can cast or change the data type of a column. In order to change data type, you would also need to use cast() function along with withColumn(). The below statement changes the datatype from String to Integer for the salary column. df.withColumn("salary",col("salary").cast("Integer")).show() 2.
df_basket1.select('Price').dtypes We use select function to select a column and use dtypes to get data type of that particular column. So in our case we get the data type of ‘Price
You’ll now see the data type that corresponds to each column in the DataFrame: Notice that the ‘name‘ column is represented as a Factor. You may then add the syntax of stringsAsFactors = FALSE to the DataFrame in order to represent that column as a character: So the complete R code would look like this:

state did not change during storage (2 weeks at 4°C) or during a freeze/thaw cycle, on a Ni2+ sepharose column using an ÄKTAxpress purification system (GE-Healthcare). Are you sure you wish to change the collation and convert the data?
To change multiple column names, we should chain withColumnRenamed functions as shown below. You can also store all columns to rename in a list and loop through to rename all columns, I will leave this to you to explore. df2 = df.withColumnRenamed("dob","DateOfBirth") \ .withColumnRenamed("salary","salary_amount") df2.printSchema()
Using infer_objects(), you can change the type of column 'a' to int64: >>> df = df.infer_objects() >>> df.dtypes a int64 b object dtype: object Column 'b' has been left alone since its values were strings, not integers. If you wanted to try and force the conversion of both columns to an integer type, you could use df.astype(int) instead. Change Column Type using withColumn () and cast () To convert the data type of a DataFrame column, Use withColumn () with the original column name as a first argument and for the second argument apply the casting method cast () with DataType on the column. 2.
Now we will convert it to datetime format using pd.to_datetime () function. Python3 df ['Date']= pd.to_datetime (df ['Date']) Use a numpy.dtype or Python type to cast entire pandas object to the same type. Alternatively, use {col: dtype, …}, where col is a column label and dtype is a numpy.dtype or Python type to cast one or more of the DataFrame’s columns to column-specific types. 2.
