Problem –
You want to know whether or not a column exist in a pandas dataframe.
Solution –
Let’s read a dataset to explain it.
import pandas as pd
url = 'https://raw.githubusercontent.com/bprasad26/lwd/master/data/clothing_store_sales.csv'
df = pd.read_csv(url)
df.head()

Now, If I want to check whether the Age column exist or not in the dataframe, I can use
if 'Age' in df.columns:
print("Yes, It Exist!")
else:
print("NO, It's Not!")
output - Yes, It Exist!
Let’s check a column that does not exist in the dataframe.
if 'Price' in df.columns:
print("Yes, It Exist!")
else:
print("NO, It's Not!")
output - NO, It's Not!
