Hi, I have struggling to efficiently convert a string list to number. Here is my problem. I have a file that contains lines such as: data_1 1 1 2 3.5 After I read the data from the file by using readlines(), each line contains a string. I use the re moduel to split the line into ['data_1', '1','1','2','3.5']. I want to create a dictionary which contains {'data_1':[1 1 2 3.5]} The problem is I coud not efficiently find a way to convert the string to number.  Does anyone know how to create such dictionary efficiently? thanks Frank
