Write a Pandas program to convert all the string values to upper, lower cases in a given pandas series. Also find the length of the string values.

 

Sample Solution:

Python Code :


import pandas as pd
import numpy as np

s = pd.Series(['X', 'Y', 'Z', 'Aaba', 'Baca', np.nan, 'CABA', None, 'bird', 'horse', 'dog'])

print("Original series:")
print(s)

print("nConvert all string values of the said Series to upper case:")
print(s.str.upper())

print("nConvert all string values of the said Series to lower case:")
print(s.str.lower())

print("nLength of the string values of the said Series:")
print(s.str.len())

Sample Output:

Original series:
0         X
1         Y
2         Z
3      Aaba
4      Baca
5       NaN
6      CABA
7      None
8      bird
9     horse
10      dog
dtype: object

Convert all string values of the said Series to upper case:
0         X
1         Y
2         Z
3      AABA
4      BACA
5       NaN
6      CABA
7      None
8      BIRD
9     HORSE
10      DOG
dtype: object

Convert all string values of the said Series to lower case:
0         x
1         y
2         z
3      aaba
4      baca
5       NaN
6      caba
7      None
8      bird
9     horse
10      dog
dtype: object

Length of the string values of the said Series:
0     1.0
1     1.0
2     1.0
3     4.0
4     4.0
5     NaN
6     4.0
7     NaN
8     4.0
9     5.0
10    3.0
dtype: float64

Two Machine Learning Fields

There are two sides to machine learning:

  • Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
  • Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
