How to Check Column Nulls and Replace: Pandas

Image
Here is a post that shows how to count Nulls and replace them with the value you want in the Pandas Dataframe. We have explained the process in two steps - Counting and Replacing the Null values. Count null values (column-wise) in Pandas ## count null values column-wise null_counts = df.isnull(). sum() print(null_counts) ``` Output: ``` Column1    1 Column2    1 Column3    5 dtype: int64 ``` In the above code, we first create a sample Pandas DataFrame `df` with some null values. Then, we use the `isnull()` function to create a DataFrame of the same shape as `df`, where each element is a boolean value indicating whether that element is null or not. Finally, we use the `sum()` function to count the number of null values in each column of the resulting DataFrame. The output shows the count of null values column-wise. to count null values column-wise: ``` df.isnull().sum() ``` ##Code snippet to count null values row-wise: ``` df.isnull().sum(axis=1) ``` In the above code, `df` is the Panda

The smart contract in Blockchain is a software application that works without human intervention. Here I have shared the Smart Contract backend process. Smart Contract Mechanism. 1. What is Smart Contract A smart contract is a protocol that can auto-execute, facilitate, verify, or enforce the negotiation of a contract. Agreement between two parties you can say as a contract. Incorporating the rules of the physical contract into the computing world, you can say as a smart contract Blockchain supports you to create smart contracts. Smart Contracts are self-executing programs that run on the blockchain and are capable of enforcing rules Using Blockchain as a platform and making an agreement or contract between more than two parties, you can say as Smart Contract. 2. Traditional Markets  3. Top Benefits of Smart Contract Currently, smart contracts are being used only in Crypto Currencies Now Smart Contracts being used in all financial transactions A smart contract ca
