Just be aware that eval() could be insecure depending on the input. Edit: Dear google user, if you want to convert a representation of a list to a list use ast as @C.B. suggested. This answer is not correct. From the ast.literal_eval docs:

Syntax: Here is the Syntax of the split() function
Example: Let’s take an example and check how to convert a string to a list.
In the above code first, we initialize a string ‘new_str’ and then use the split() method and pass whitespace as a delimiter which splits the words of the string, and stores them into the list. Here is the Screenshot of the following given code Python string to listRead Remove character from string Python (35 Examples) Convert a string to a list in PythonBy using the Python list() function we can perform this particular task and this method takes iterable objects and converts them into the list. Here is the code of string to list in Python
In this example, we use the concept of strip() function and it will remove spaces from the string at the first and the end of the string. Here is the execution of the following given code Python string to listRead How to create a string in Python Python string to list of characters

Here is the Output of the following given code Python string to list by a delimiterRead How to concatenate strings in python Python string to list of floats
Source Code:
In this example, we have created a string ‘flo_str’ and assign them float values. Now by using the map() function we have passed float data type as an argument and store them into a ‘new_item’ variable. Output: Python string to list of floatsRead How to Convert Python string to byte array with Examples Another example by using list comprehension and eval() method
Example:
Here is the Screenshot of the following given code Python string to list of floatsBy using for loop and split() method we can a string to a list of floats in Python Source Code:
In this example, we have created a list of items by space in a string, we can use the split() and along with use for loop to iterate each item in a given list. After that use float datatype to convert each item to a float number. Screenshot: Python string to list of floatsRead How to convert a String to DateTime in Python Python string to list array

How do I split a string into a list without splitting?What are other ways to split a string without using the split() method?. Loop through the strings. ... . Create a new string to keep track of the current word ( word ).. Loop through the characters in each of these strings.. How do you convert an entire string to a list in Python?To do this we use the split() method in string. The split method is used to split the strings and store them in the list. The built-in method returns a list of the words in the string, using the “delimiter” as the delimiter string.
Can we convert string to list in Python?Python String is a sequence of characters. We can convert it to the list of characters using list() built-in function.
