But when working with comma separated values we’ll typically read it from a file that’s been exported from spreadsheet or database programs. For the sake of clarity, we’ll simply create a string where words are separated by commas. We can see one example of this with something known as a csv or comma separated value file.
We have a wide variety of methods to convert strings into other formats once we’ve properly split the elements into a character list. We can then use a join function, cut the strings on whitespace or look for delimiter values to use as indicators of a point where converting string elements might end. The Python programming language often takes in information as a string and then gives us the option to convert it into other formats. This is even true if we’re reading in data that originates from something like a floating point number. Likewise, we’ll usually read data from outside sources into a split string value. Basically, all plain text is a given string. One of the more difficult aspect of working with strings is the sheer scope of the subject. Of course there’s a large number of other twists on strings to consider. Finally, we print the first list comprehension to show that it’s behaving as a standard Python list. In this example we import Python’s json library to convert a created json string into a list. OurList = json.loads(jsonConvertedString)
Python convert string to list how to#
The following Python code will show how to use those functions to convert a json string to a list. But thankfully, json tools are part of the standard Python library. This might seem like a difficult usage scenario. This is accomplished in the final line of the script.īut what about more complex cases? Python code often works with json string types.
In fact, we’ll see that in the next part of the Python program when we print it to screen. Split is an immensely useful given string method that can take a string, convert list items, and return it as a standard Python list. We then use the split function on the newly created ourString variable. Our Python convert string to list example begins by simply defining a string literal. We can begin with a quick and simple demonstration of how we might convert a string into a Python list. In particular, we’re able to manipulate and even convert between these objects fairly easily. But both data type are treated very differently in Python than programmers familiar with other languages might expect. Meanwhile, lists are quite similar to arrays. Strings in Python programming are generally analogous to the same variable in other languages. Strings and lists are two perfect examples of Python’s flexibility. This is in large part due to how the language handles data type structures. Python is well known as one of the more versatile programming languages.
