# Pandas: Extract only number from the specified column of a given DataFrame

## Pandas: String and Regular Expression Exercise-27 with Solution

Write a Pandas program to extract only number from the specified column of a given DataFrame.

Sample Solution:

Python Code :

``````import pandas as pd
import re as re
pd.set_option('display.max_columns', 10)
df = pd.DataFrame({
'company_code': ['c0001','c0002','c0003', 'c0003', 'c0004'],
'address': ['7277 Surrey Ave.','920 N. Bishop Ave.','9910 Golden Star St.', '25 Dunbar St.', '17 West Livingston Court']
})
print("Original DataFrame:")
print(df)
def find_number(text):
num = re.findall(r'[0-9]+',text)
return " ".join(num)
print("\Extracting numbers from dataframe columns:")
print(df)
``````

Sample Output:

```Original DataFrame:
0        c0001          7277 Surrey Ave.
1        c0002        920 N. Bishop Ave.
2        c0003      9910 Golden Star St.
3        c0003             25 Dunbar St.
4        c0004  17 West Livingston Court
\Extracting numbers from dataframe columns:
0        c0001          7277 Surrey Ave.   7277
1        c0002        920 N. Bishop Ave.    920
2        c0003      9910 Golden Star St.   9910
3        c0003             25 Dunbar St.     25
4        c0004  17 West Livingston Court     17
```
