I'am working on a project in python. I've got a webserver running that receives post data. I want to turn that data into sepparate variables so that I can do something else with it.

I've got this:

for item in (post_data.decode("utf-8").split('&')):

That returns this:


but I want to set that as variables so I can do:


and return John

We can use two .split() functions and then create a dictionary. From here we can print name and lastname.

s = 'name=john lastname=smith'
dicta = (dict([i.split('=') for i in s.split()]))

print(dicta['name']) # => john
print(dicta['lastname']) # => smith

also using dictionary comprehension

dicta = {i.split('=')[0]: i.split('=')[1] for i in s.split()}

An Introduction to Working with Strings in Python 3, Here we insert a string into another string: The values do not have to be strings, they can be numbers and other Python objects. attractive option, which is to use the new formatted string literal (f-string) syntax to insert variable values. Storing Strings in Variables. Variables are symbols that you can use to store data in a program. You can think of them as an empty box that you fill with some data or value. Strings are data, so we can use them to fill up a variable. Declaring strings as variables can make it easier for us to work with strings throughout our Python programs.

If the output is a single string: 'name=john lastname=smith' you can use a list comp like

[j.split('=')[1] for j in n.split()]

Python Variables and Assignment, There are 4 approaches I am aware of for achieving this on python (Python 3):. 1) Concatenation: You can do this using + for joining 2 strings,  Concatenate a list of strings into one string: join() The string method join() can be used to concatenate a list of strings into a single string. Built-in Types - str - join() — Python 3.8.1 documentation; Write as follows:

You can use a generator expression to split the strings with = and unpack the output to a tuple of variables:

name, lastname = (p.split('=', 1)[1] for p in post_data.decode("utf-8").split('&'))

String and Writing Programs, Concatenating With the + Operator; Going From a List to a String in Python With .​join If you concatenate or repeat a string stored in a variable, you will have to  What is a String Variable? A string is a sequence of characters enclosed within the single or double quotes. Many programming languages have a character data type. However, in Python, strings are the sequence of unicode characters. Python does not have character data type to store the string. It has a string as a data type to store a sequence of characters in a variable. Create String Variable

How do you assign a string to a variable in Python? 103204934000. In this example, Python does the math for us, subtracting 813 from the variable my_int to return the sum 103204934000. Speaking of math, variables can be set equal to the result of a math equation. Let’s add two numbers together and store the value of the sum into the variable x: x = 76 + 145.

You can look into how variables work in Python in the Python variables tutorial. For example, you can assign a character 'a' to a variable single_quote_character . Read “Python 2 vs Python 3: Practical Considerations” for more information about the differences between Python 2 and Python 3. Converting with Strings. A string is a sequence of one or more characters (letters, numbers, symbols). Strings are a common form of data in computer programs, and we may need to convert strings to numbers or

One thing to note is that Python cannot concatenate a string and integer. In order to pass variables to a string you must call upon the format()  Python does not support a character type; these are treated as strings of length one, thus also considered a substring. To access substrings, use the square brackets for slicing along with the index or indices to obtain your substring.

  • How about creating a dictionary and doing dict_name['name'] ?
  • This worked for my, I had to change it up a bit to work with my postdata (var s)
