Pandas: Check whether only space is present in a given column of a DataFrame

Pandas: String and Regular Expression Exercise-14 with Solution

Write a Pandas program to check whether only space is present in a given column of a DataFrame.

Sample Solution:

Python Code :

``````import pandas as pd
df = pd.DataFrame({
'company_code': ['Abcd','EFGF ', '  ', 'abcd', ' '],
'date_of_sale ': ['12/05/2002','16/02/1999','25/09/1998','12/02/2022','15/09/1997'],
'sale_amount': [12348.5, 233331.2, 22.5, 2566552.0, 23.0]})

print("Original DataFrame:")
print(df)
print("\nIs space is present?")
df['company_code_is_title'] = list(map(lambda x: x.isspace(), df['company_code']))
print(df)

``````

Sample Output:

```Original DataFrame:
company_code date_of_sale   sale_amount
0         Abcd    12/05/2002      12348.5
1        EFGF     16/02/1999     233331.2
2                 25/09/1998         22.5
3         abcd    12/02/2022    2566552.0
4                 15/09/1997         23.0

Is space is present?
company_code          ...          company_code_is_title
0         Abcd          ...                          False
1        EFGF           ...                          False
2                       ...                           True
3         abcd          ...                          False
4                       ...                           True

[5 rows x 4 columns]
```

Python: Time library

Time library provides lots of time related functions and methods and is good to know whether you're developing a website or apps and games or working with data science or trading financial markets. Time is essential in most development pursuits and Python's standard time library comes very handy for that.

Let's check out a few simple examples:

moment=time.strftime("%Y-%b-%d__%H_%M_%S",time.localtime())

```import time
time_now=time.strftime("%H:%M:%S",time.localtime())
print(time_now)
date_now=time.strftime("%Y-%b-%d",time.localtime())
print(date_now)
```

Output:

```11:36:34
2020-Nov-30```
