![]() ![]() ![]() The output is: Using the tuple() FunctionĪ tuple is an immutable version of a list. You can observe this in the following example. After execution, it will return a list containing all the characters of the input string. To break a string into characters, we will pass the input string to the list() function. It takes the iterable object as its input argument and returns a list containing the elements of the iterable object. The list() constructor is used to create a list from any iterable object such as a string, set, or tuple in python. String to List of Characters Using the list() Function in Python Hence, we are able to get the same results in fewer lines of code. In this example, we have used list comprehension instead of the for loop. You can split a string into a list of characters using list comprehension as shown below. It’s a better alternative to the approach using a for loop and the append() method as we can convert any iterable object into a list with a single python statement. List comprehension is used to create a list from elements of an existing iterable object in python. ![]() String to List of Characters Using List Comprehension In the above example, we have split the string "Python For Beginners" into a list of characters. Output: The input string is: Python For Beginners The append() method, when invoked on a list, takes a character as its input argument and appends it to the end of the list.Īfter execution of the for loop, we will get all the characters of the string in the list. While iteration, we will add each character of the string to the list using the append() method. Then, we will iterate through the characters of the string using a python for loop. To split a string using the for loop, we will first define an empty list to contain the output characters. Hence, we can access the character of a string one by one using a for loop. Split a String Into Characters Using the for Loop in PythonĪ string in python is an iterable object. Let us discuss other approaches for this. So, we cannot use the split() method to split a python string into characters. However, the program runs into a ValueError exception saying that you have used an empty separator. ![]() In this example, we have passed an empty string as a separator to split the string into characters. One can say that we can use an empty string to split a string into characters. A very old thread on python-dev seems to indicate that it has something to do with chaining the output, but since the Python methods don't do the same, I'm not sure if that's still relevant.The input string is: Python For Beginners I'm not entirely sure what the reasoning behind PyString_Decode working this way is. Py_unicode = PyString_AsDecodedObject(py_string, "windows_1252", "replace") Py_string = PyString_FromStringAndSize(c_string, 1) I believe you'll need to do two calls - but you can use PyString_AsDecodedObject rather than calling the python "decode" method. PyString_AsDecodedString does PyString_AsDecodedObject, but then tries to convert the resulting unicode object into a string object with the default encoding (for you, looks like that's ASCII). The problem here arises from PyString_AsDecodedString, rather than PyString_AsDecodedObject. IOW, it does basically what you're doing in your second example - converts to a string, then decode the string. V = PyString_AsDecodedString(str, encoding, errors) Str = PyString_FromStringAndSize(s, size) PyString_Decode does this: PyObject *PyString_Decode(const char *s, The following code works around the problem by using PyString_FromString to create a Python string of the undecoded bytes, then calling its decode method: #include ĭecoded = PyObject_CallMethod(raw, "decode", "s", "windows_1252") The error message is UnicodeEncodeError: 'ascii' codec can't encode character u'\u201c' in position 0: ordinal not in range(128), which indicates that the ascii encoding is used even though we specify windows_1252 in the call to PyString_Decode. Py_string = PyString_Decode(c_string, 1, "windows_1252", "replace") I have attempted to use PyString_Decode, but it always fails when there are non-ASCII characters in the string. The Python string should in general be of type unicode-for instance, a 0x93 in Windows-1252 encoded input becomes a u'\u0201c'. How do I decode the contents of this char array into a Python string? Suppose the C program reads some bytes from a file into a char array and learns (somehow) that the bytes represent text with a certain encoding (e.g., ISO 8859-1, Windows-1252, or UTF-8). I have embedded a Python interpreter in a C program. ![]()
