python binary search implementation code example
Example 1: binary search in python
def binary_search(item_list,item):
first = 0
last = len(item_list)-1
found = False
while( first<=last and not found):
mid = (first + last)
if item_list[mid] == item :
found = True
else:
if item < item_list[mid]:
last = mid - 1
else:
first = mid + 1
return found
Example 2: binary search in python
def binary_search(group, suspect):
group.sort()
midpoint = len(group)
while(True):
if(group[midpoint] == suspect):
return midpoint
if(suspect > group[midpoint]):
group = group[midpoint]
if(suspect < group[midpoint]):
group = group[0: midpoint]
midpoint = (len(group)
