Interconversion of data is a popular problem developers generally deal with. One can face a problem to convert tuple string to integer tuple. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using tuple() + int() + replace() + split()
The combination of above methods can be used to perform this task. In this, we perform the conversion using tuple() and int(). Extraction of elements is done by replace() and split().




# Python3 code to demonstrate working of 
# Convert Tuple String to Integer Tuple
# Using tuple() + int() + replace() + split()
  
# initializing string 
test_str = "(7, 8, 9)" 
  
# printing original string 
print("The original string is : " + test_str)
  
# Convert Tuple String to Integer Tuple
# Using tuple() + int() + replace() + split()
res = tuple(int(num) for num in test_str.replace('(', '').replace(')', '').replace('...', '').split(', '))
  
# printing result 
print("The tuple after conversion is : " + str(res)) 

Output :

The original string is : (7, 8, 9)
The tuple after conversion is : (7, 8, 9)

 

Method #2 : Using eval()
This is recommended method to solve this task. This performs the interconversion task internally.




# Python3 code to demonstrate working of 
# Convert Tuple String to Integer Tuple
# Using eval()
  
# initializing string 
test_str = "(7, 8, 9)" 
  
# printing original string 
print("The original string is : " + test_str)
  
# Convert Tuple String to Integer Tuple
# Using eval()
res = eval(test_str)
  
# printing result 
print("The tuple after conversion is : " + str(res)) 

Output :

The original string is : (7, 8, 9)
The tuple after conversion is : (7, 8, 9)
