An example that uses this code Compute The Average, Min, Max And Mode Of A List In Python.

```
def avg(list):

sum = 0

for elm in list:
sum += elm

return sum/(len(list)*1.0)

def min(list):

min = list[0]

for elm in list[1:]:
if elm < min:
min = elm

return min

def max(list):

max = list[0]

for elm in list[1:]:
if elm > max:
max = elm

return max

def mode(list):

d = {}
for elm in list:
try:
d[elm] += 1
except(KeyError):
d[elm] = 1

keys = d.keys()
max = d[keys[0]]

for key in keys[1:]:
if d[key] > max:
max = d[key]

max_k = []
for key in keys:
if d[key] == max:
max_k.append(key),
return max_k,max

def range_of_list(list):
return max(list) - min(list)

def main():

list = [3,4,1,20,102,3,5,67,39,10,1,4,34,1,6,107,99]

print "The average element of the list is: " + str(avg(list))
print "The minimum value in the list is: " + str(min(list))
print "The maximum value in the list is: " + str(max(list))

keys = mode(list)
print "The mode of the list is: " + ','.join(map(str,keys[0])) + " with the mode of: " + str(keys[1])

print "The range of the list is: " + str(range_of_list(list))

if __name__ == "__main__":
main()

```
