In order to convert PySpark column to Python List you need to first select the column and perform the collect() on the DataFrame. By default, PySpark DataFrame collect() action returns results in Row() Type but not list hence either you need to pre-transform using map() transformation or ...
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...

Example 1: Extract pandas DataFrame Column as List In Example 1, I’ll demonstrate how to convert a specific column of a pandas DataFrame to a list object in Python. For this task, we can use the tolist function as shown below:
columnsrepresent the columns names for the data indexrepresent the row numbers/values We can also create a DataFrame using dictionary by skipping columns and indices. Example: Python Program to create a dataframe for market data from a dictionary of food items by specifying the column names. ...
Using the TEXTJOIN function is one of the most efficient ways to convert column to row with comma. The TEXTJOIN function returns a text string as output where the given text inputs are joined by a specified delimiter. Steps: Enter the following formula in cell C5. =TEXTJOIN(",",TRUE,B5:...
2) Using a list with index & column names We can create the data frame by giving the name to the column and indexing the rows. Here we also used the same DataFrame constructor as above. Example: # import pandas as pd import pandas as pd # List1 lst = [['apple', 'red', 11], ...
