How to Check Column Nulls and Replace: Pandas

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

Blockchain Technology: 11 Exclusive Benefits

Here are the benefits of blockchain technology. Less maintenance and its distributable nature made the blockchain technology hot in the market.     The applications that used blockchain technology Viz: Banks, Share markets, Government Bodies, and Big Corporations.  What is Blockchain Blockchain stores each transaction in Blocks. No one can tamper or change the details. The people who are making a transaction in the Blockchain world both have the same copies. he parties involved cannot changes these records. So it is robust. Advantages of distributed ledger technology (Blockchain) The distributed nature of ledger details. Distributed data available to all parties, and cannot tamper the data. Every transaction is Public. That means only people who have access can see the information. It stores all records permanently. One cannot edit or manipulate the data. Data-hacking is not possible since it is distributed. Unlike centralized processing, the Blockchain is much faster. And verification
