 Whether you're a beginner or brushing up on your skills, these are the real-world questions Python learners ask most about key libraries in data science. Let’s dive in! 🐍 🐼 Pandas: Data Manipulation Made Easy 1. How do I handle missing data in a DataFrame? df.fillna( 0 ) # Replace NaNs with 0 df.dropna() # Remove rows with NaNs df.isna(). sum () # Count missing values per column 2. How can I merge or join two DataFrames? pd.merge(df1, df2, on= 'id' , how= 'inner' ) # inner, left, right, outer 3. What is the difference between loc[] and iloc[] ? loc[] uses labels (e.g., column names) iloc[] uses integer positions df.loc[ 0 , 'name' ] # label-based df.iloc[ 0 , 1 ] # index-based 4. How do I group data and perform aggregation? df.groupby( 'category' )[ 'sales' ]. sum () 5. How can I convert a column to datetime format? df[ 'date' ] = pd.to_datetime(df[ 'date' ]) ...

With the help of a small wireless device that plugs into the diagnostic port, Metromile offers a “per-mile” usage-based insurance. Often, low-mileage drivers overpay for insurance because they’re subsidizing those who drive the most. Insurance Calculation But since the number one risk indicator for drivers is time on the road, Metromile can offer insurance pro-rata by tracking the miles driven. #Mile-based insurance an application of IoT: According to wiki: Usage-based insurance (UBI) -also known as pay as you drive (PAYD) and pay how you drive (PHYD) and mile-based auto insurance   is a type of vehicle insurance whereby the costs are dependent upon the type of vehicle used, measured against time, distance, behavior, and place. This differs from traditional insurance, which attempts to differentiate and reward "safe" drivers, giving them lower premiums and/or a...

IoT Architecture for very new developers: part 1 of 6

-
What is the architecture of internet of things -The three-layer DCM classification is more about the IoT value chain than its system architecture at run time. I hope you enjoyed with my previous  post-5  on IOT. For system architecture, some have divided the IoT system into as many as nine layers, from bottom to top: devices connectivity data collection communication device management. data rules administration applications integration While large companies such as IBM, Oracle, Microsoft, and others have comprehensive solutions, products, and services that cover almost the entire value chain. Recommendation for you:     Part-2  |  Part-1 Broadly IOT architecture can be classified as three layers: Device Layer Communication Layer Mangement Layer Device Layer: Devices or assets can be categorized as two groups: those that have inherent intelligence such as electric meters or heating, ventilation, and air-conditioning (HVA...
