Creating a Pandas Series from Lists

A Series is a one-dimensional labeled array capable of holding any data type (integers, strings, floating point numbers, Python objects, etc.). It has to be remembered that unlike Python lists, a Series will always contain data of the same type.

Let’s see how to create a Pandas Series from lists.

Method #1 : Using Series() method without any argument.

# import pandas as pd
import pandas as pd

# create Pandas Series with default index values
# default index ranges is from 0 to len(list) - 1
x = pd.Series(['Geeks', 'for', 'Geeks'])

# print the Series
print(x)

Output :


Method #2 : Using Series() method with 'index' argument.

# import pandas lib. as pd
import pandas as pd

# create Pandas Series with define indexes
x = pd.Series([10, 20, 30, 40, 50], index =['a', 'b', 'c', 'd', 'e'])

# print the Series
print(x)

Output :

Another example:

# import pandas lib. as pd
import pandas as pd

ind = [10, 20, 30, 40, 50, 60, 70]

lst = ['Geeks', 'for', 'Geeks', 'is',
            'portal', 'for', 'geeks']

# create Pandas Series with define indexes
x = pd.Series(lst, index = ind)

# print the Series
print(x)

Output:

Method #3: Using Series() method with multi-list

# importing pandas
import pandas as pd

# multi-list
list = [ ['Geeks'], ['For'], ['Geeks'], ['is'],
         ['a'], ['portal'], ['for'], ['geeks'] ]

# create Pandas Series
df = pd.Series((i[0] for i in list))

print(df)

Output:
