Python - Test Similar Data Type in Tuple

Python – Test Similar Data Type in Tuple

Last Updated : 08 Jun, 2020

Sometimes, while working with Python tuples, we can have a problem in which we need to test if all the elements in tuple have same data type. This kind of problem can have application across all domains such as web development and day-day programming. Let’s discuss certain ways in which this task can be performed.

Input : test_tuple = (5, 6, 7, 3, "Gfg")
Output : False

Input : test_tuple = (2, 3)
Output : True

Method #1 : Using loop + isinstance()
The combination of above functions can be used to solve this problem. In this, we perform the checking of data types using isinstance() and iteration is done as brute force way to account for all the elements.

# Python3 code to demonstrate working of 
# Test Similar Data Type in Tuple
# Using isinstance() + loop
  
# initializing tuple
test_tuple = (5, 6, 7, 3, 5, 6)
  
# printing original tuple
print("The original tuple : " + str(test_tuple))
  
# Test Similar Data Type in Tuple
# Using isinstance() + loop
res = True
for ele in test_tuple:
    if not isinstance(ele, type(test_tuple[0])):
        res = False 
        break
  
# printing result 
print("Do all elements have same type ? : " + str(res))

Output :

The original tuple : (5, 6, 7, 3, 5, 6)
Do all elements have same type ? : True

Method #2 : Using all() + isinstance()
The combination of above functions can also be used to solve this problem. In this, we test for all the values using all() and isinstance() is used to check for data type.

# Python3 code to demonstrate working of 
# Test Similar Data Type in Tuple
# Using all() + isinstance()
  
# initializing tuple
test_tuple = (5, 6, 7, 3, 5, 6)
  
# printing original tuple
print("The original tuple : " + str(test_tuple))
  
# Test Similar Data Type in Tuple
# Using all() + isinstance()
res = all(isinstance(ele, type(test_tuple[0])) for ele in test_tuple)
  
# printing result 
print("Do all elements have same type ? : " + str(res))

Output :

The original tuple : (5, 6, 7, 3, 5, 6)
Do all elements have same type ? : True
