Python | Convert String to tuple list
• Last Updated : 24 Jun, 2020

Sometimes, while working with Python strings, we can have a problem in which we receive a tuple, list in the comma-separated string format, and have to convert to the tuple list. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using loop + `split() + replace()`
This is a brute force method to perform this task. In this, we perform the task of extracting and remaking the tuples to list in a loop using split() and replace() functionalities.

 `# Python3 code to demonstrate working of``# Convert String to tuple list``# using loop + replace() + split()`` ` `# initializing string ``test_str ``=` `"(1, 3, 4), (5, 6, 4), (1, 3, 6)"`` ` `# printing original string ``print``(``"The original string is : "` `+` `test_str)`` ` `# Convert String to tuple list``# using loop + replace() + split()``res ``=` `[]``temp ``=` `[]``for` `token ``in` `test_str.split(``", "``):``    ``num ``=` `int``(token.replace(``"("``, "``").replace("``)``", "``"))``    ``temp.append(num)``    ``if` `")"` `in` `token:``       ``res.append(``tuple``(temp))``       ``temp ``=` `[]`` ` `# printing result``print``(``"List after conversion from string : "` `+` `str``(res))`
Output :
```The original string is : (1, 3, 4), (5, 6, 4), (1, 3, 6)
List after conversion from string : [(1, 3, 4), (5, 6, 4), (1, 3, 6)]
```

Method #2: Using `eval()`
This inbuilt function can also be used to perform this task. This function internally evaluates the string and returns the converted list of tuples as desired.

 `# Python3 code to demonstrate working of``# Convert String to tuple list``# using eval()`` ` `# initializing string ``test_str ``=` `"(1, 3, 4), (5, 6, 4), (1, 3, 6)"`` ` `# printing original string ``print``(``"The original string is : "` `+` `test_str)`` ` `# Convert String to tuple list``# using eval()``res ``=` `list``(``eval``(test_str))`` ` `# printing result``print``(``"List after conversion from string : "` `+` `str``(res))`
Output :
```The original string is : (1, 3, 4), (5, 6, 4), (1, 3, 6)
List after conversion from string : [(1, 3, 4), (5, 6, 4), (1, 3, 6)]
```
