Remove 1st Column Pandas Code Example
Snippet 1 df.drop(‘col_name’,1) #1 drop column / 0 drop row Snippet 2 To delete rows and columns from DataFrames, Pandas uses the “drop” function. To delete a column, or multiple columns, use the name of the column(s), and specify the “axis” as 1. Snippet 3 df = df.drop(df.columns[[0, 1, 3]], axis=1) # df.columns is zero-based… Continue reading Remove 1st Column Pandas Code Example

Pandigit checking in Fibonacci Numbers
Project Euler problem 104 is to write an algorithm to determine the first Fibonacci number for which the first 9 digits are 1-9 pandigital and the last 9 digits are also pandigital, where pandigital means that these digits are a permutation of 1 to 9. Because the answer is going to be a very large… Continue reading Pandigit checking in Fibonacci Numbers
