First and last character of each word to upper case: 0 PhP 1 PythoN 2 JavA 3 C# dtype: object Click me to see the sample solution 25.Write a Pandas program to calculate the number of characters in each word in a given series.
Pandas will extract the data from that CSV into a DataFrame — a table, basically — then let you do things like: Calculate statistics and answer questions about the data, like What's the average, median, max, or min of each column? Does column A correlate with column B? What does ...
If we want to extract thebrand modifier(last two characters) from the string, we will usenegative indexingin the string slicing. We will pass the start index-2(the second last character’s index) and leave the end index empty. It will automatically take the last two characters from the st...
