In this article, we will discuss how to convert a Pandas series to a Python List and it’s type. This can be done using the tolist() method.
Example 1:
Python3
import pandas as pd evenNumbers = [2, 4, 6, 8, 10] evenNumbersDs = pd.Series(evenNumbers) print("Pandas Series and type") print(evenNumbersDs) print(type(evenNumbersDs)) print("\nConvert Pandas Series to Python list") print(evenNumbersDs.tolist()) print(type(evenNumbersDs.tolist())) |
Output:
In the above example, we are passing Panda series data as evenNumbers . As index is not given, by default 0 is taken
Example 2:
Python3
import pandas as pd import numpy as np data = np.array(['ant','bat','cat','dog']) series = pd.Series(data,index=[100,101,102,103]) print(series) print(type(series)) print("\nConvert Pandas Series to Python list") print(series.tolist()) print(type(series.tolist())) |
Output:
In the above example, we are passing Panda series data as np.array([‘ant’,’bat’,’cat’,’dog’]).
Index as [100,101,102,103]
Example 3:
Python3
# Series from dictionary import pandas as pd import numpy as np marks = {'Maths' : 100., 'Physics' : 90., 'Chemistry' : 85.} series = pd.Series(marks) print(series) print(type(series)) print("\nConvert Pandas Series to Python list") print(series.tolist()) print(type(series.tolist())) |
Output:
Example 4:
Python3
# Get First 3 student marks and # convert as list import pandas as pd series = pd.Series([100, 90, 80, 90, 85], index=['Student1', 'Student2', 'Student3', 'Student4', 'Student5']) # retrieve the first three element print(series[:3]) print(series[:3].tolist()) print(type(series[:3].tolist())) |
Output:
