Pandas Series

A Pandas series is like a column in a table.

import pandas as pd

a = [1, 7, 2]

myvar = pd.Series(a)

print(myvar)

0    1
1    7
2    2
dtype: int64

 

• Create Labels

Example

import pandas as pd

a = [1, 7, 2]

myvar = pd.Series(a, index = ["x", "y", "z"])

print(myvar)

x    1
y    7
z    2
dtype: int64

 

• Key/Value Objects as Series 

Example 

Create a Series using only data from "day1" and "day2".

import pandas as pd

calories = {"day1": 420, "day2": 380, "day3": 390}

myvar = pd.Series(calories, index = ["day1", "day2"])

print(myvar)

day1    420
day2    380
dtype: int64
