Python Pandas: Find length of string in dataframe

Question

Hi. I want to find the length of the string stored in each cell of the dataframe. What code should I use to do this?

Answer 1

To find the length of strings in a data frame you have the len method on the dataframes str property. But to do this you need to call this method on the column that contains the string data.

For example:

import pandas as pd

data = pd.DataFrame({

    'age' : [15, 17, 20, 14, 25],

    'name': ["Sample", "New User", "My Name", "Jane Doe", "John Doe"]

})

data['name'].str.len()

You'll get the following output:

0    6

1    8

2    7

3    8

4    8

Name: name, dtype: int64
