+# Question 39
+### Level 1
+
+**Question:**
+
+***Write a program to generate and print another tuple whose values are even numbers in the given tuple (1,2,3,4,5,6,7,8,9,10).***
+
+----------------------
+### Hints: Use "for" to iterate the tuple. Use tuple() to generate a tuple from a list.
+
+-------------------
+**My Solution: Python 3**
+```
+tp = (1,2,3,4,5,6,7,8,9,10)
+li = list()
+for i in tp:
+if tp[i]%2 == 0:
+li.append(tp[i])
+
+tp2 = tuple(li)
+print tp2
+```
+----------------
+**My Solution: Python 3**
+```
+tpl = (1,2,3,4,5,6,7,8,9,10)
+tpl1 = tuple(i for i in tpl if i%2 == 0)
+print(tpl1)
+```
+**OR**
+```
+tpl = (1,2,3,4,5,6,7,8,9,10)
+tpl1 = tuple(filter(lambda x : x%2==0,tpl)) # Lambda function returns True if found even element.
+ # Filter removes data for which function returns False
+print(tpl1)
+```
