+### bubble_sort
+Bubble_sort uses the technique of comparing and swapping
+
+```python
+def bubble_sort(arr):
+    for passnum in range(len(arr)-1,0,-1):
+        for i in range(passnum):
+            if arr[i]>arr[i+1]:
+                temp = arr[i]
+                arr[i] = arr[i+1]
+                arr[i+1] = temp
+
+```
+
+```python
+arr = [54,26,93,17,77,31,44,55,20]
+bubble_sort(arr)
+print("sorted %s" %arr) # [17,20,26,31,44,54,55,77,91]
+```
