Thanks. That fixed the problem.
## --------------------------------------------
## Generate a list
## --------------------------------------------
def GenerateList():
array = []
for i in xrange(10):
array.append(i)
return array
## -----------------------------------------------
# Entry Point to the whole program
## -----------------------------------------------
def main():
mylist = GenerateList()
minnumber = min(mylist)
for num in mylist:
print num - minnumber
## --------------------------------
# Entry-point to the whole program
## --------------------------------
main()
This is how my revised code looks like
