Pandas: Check whether two given words present in a specified column of a given DataFrame
Pandas: String and Regular Expression Exercise-35 with Solution
Write a Pandas program to check whether two given words present in a 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': ['9910 Surrey Ave.','92 N. Bishop Ave.','9910 Golden Star Ave.', '102 Dunbar St.', '17 West Livingston Court']
})
print("Original DataFrame:")
print(df)
def test_and_cond(text):
result = re.findall(r'(?=.*Ave.)(?=.*9910).*', text)
return " ".join(result)
df['check_two_words']=df['address'].apply(lambda x : test_and_cond(x))
print("\nPresent two words!")
print(df)
Sample Output:
Original DataFrame: company_code address 0 c0001 9910 Surrey Ave. 1 c0002 92 N. Bishop Ave. 2 c0003 9910 Golden Star Ave. 3 c0003 102 Dunbar St. 4 c0004 17 West Livingston Court Present two words! company_code address check_two_words 0 c0001 9910 Surrey Ave. 9910 Surrey Ave. 1 c0002 92 N. Bishop Ave. 2 c0003 9910 Golden Star Ave. 9910 Golden Star Ave. 3 c0003 102 Dunbar St. 4 c0004 17 West Livingston Court

Python: Cache results with decorators
There is a great way to cache functions with decorators in Python. Caching will help save time and precious resources when there is an expensive function at hand.
Implementation is easy, just import lru_cache from functools library and decorate your function using @lru_cache.
from functools import lru_cache @lru_cache(maxsize=None) def fibo(a): if a <= 1: return a else: return fibo(a-1) + fibo(a-2) for i in range(20): print(fibo(i), end="|") print("\n\n", fibo.cache_info())
Output:
0|1|1|2|3|5|8|13|21|34|55|89|144|233|377|610|987|1597|2584|4181| CacheInfo(hits=36, misses=20, maxsize=None, currsize=20)
