-* Tutorial Plan 
-** Doing simple statistical operations in Python  
-** Using loadtxt to solve statistics problem
+* Question
+  - In the given file football.txt at path /home/fossee/football.txt , 
+    one column is player name,second is goals at home 
+    and third goals away.
+    - Find the total goals for each player
+    - Mean home and away goals
+    - Standard deviation of home and away goals 
+
+* Solution
+#+begin_src python
+  L=loadtxt('/home/amit/football.txt',usecols=(1,2),
+            delimiter=',')
+  sum(L,1)
+  mean(L,0)
+  std(L,0)
+#+end_src python
