The method looks like this: datetime.strptime(datestring, format) The datestring is the string that holds what we want to convert. Before using this method, you have to import the json library in python using the import keyword. One of the very helpful methods that we can use within the datetime module is the strptime method that allows us to convert a string to a date (or in our case, a datetime ). # return the result of the calculation - this value is placed in the new field. Below are 3 methods to convert string to the dictionary in python: 1) Using json.loads() You can easily convert python string to the dictionary by using the inbuilt function of loads of json library of python. If you actually meant: "how do I calculate numeric a value in Field Calculator if my inputs are text fields", then you need to do something like: The way to specify the number system is to use base: > int('0x12F', base16) 303 Now, int () understands you are passing a hexadecimal string and expecting a decimal integer. On other hand, to convert all the string items in a list into int we can use int () method as follows. When you pass a string to int (), you can specify the number system that you’re using to represent the integer.

We can also use float () method to convert it into a float variable. Yes, I know this is a huge pain in the ass. In above program we’re using int () method to convert string to int. long) and use the field calculator to set the new field = to the old field, Arc will handle the conversion from string to number (or whatever) then you can delete the old field. You have to create a new field, of the desired type (i.e. In this example we have defined a custom function name StrtoBinary first, we are using ord () to get numbers that represent Unicode of given characters in a string and append them to a list. Math Module,ord (),bin () to convert string to binary. turning a string field into a long field). Python Program to convert string to binary in Python. As far as I know, you cannot change the type of an existing field (i.e.

What if we need a list of characters present in a string? In that case, direct type conversion from string to list in Python using the list() method does the job for us.Ĭertainly, if the input string is something like “abcd”, typecasting the string into a list using the list() method gives us a list having the individual characters ‘a’, ‘b’, ‘c’, ‘d’ as its elements.
