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)
