+Draft a python script to solve the following questions. thanks
+
+# Requirement
+Please use recursion to define and test a function to calculate the sum of a list of numbers.
+
+# procedure
+- let's think it step by step
+- leave me comment with your code
+- solve with recursion
+- write your code in `def list_sum_Recur(num_list):` , with comment `# implementation here`
+- write a sample function to use it, with comment `# test here`
+'''
