Find Missing Element in a Series Using Python

Solution

To solve this, we will follow the steps given below −

• Define a Series.

• Create a for loop and access the data from start to end elements. Set if condition to check the data is present or not.

If the value is not in the range then append it to the list. Finally, sort and print the values.

for i in range(data[0],data[length-1]):
   if(i not in data):
      l1.append(i)
   else:
      l1.append(i)

Example

Let us see the following implementation to get a better understanding.

import pandas as pd
import numpy as np
l = [1,2,3,6,7]
l1 = []
data = pd.Series(l)
length = len(data)
for i in range(data[0],data[length-1]):
   if(i not in data):
      l1.append(i)
   else:
      l1.append(i)
l1.sort()
data = pd.Series(l1)
print(data)

Output

0    1
1    2
2    3
3    4
4    5
5    6
