unable to add the variable value into a query using f string in python

Question

I am having a JSON script and I want to add a variable value into it using f-string in python but I was unable to do it.

name = "harsha"
query = """mutation {
                createUsers(input:{
                user_name: f"{name}"
                  })
                  {
                    users{
                      user_name
                    }
                  }
              }
        """

when i am printing query i am getting the same value not the change value harsha

Everything within the triple quotes is interpreted as being part of the string, not as code. Move the f in front of the triple quotes to have it be interpreted as an f-string.

This will require escaping the rest of the braces, so you'll end up with this.

name = "harsha"
query = f"""mutation {{
                createUsers(input:{{
                user_name: {name}
                  }})
                  {{
                    users{{
                      user_name
                    }}
                  }}
              }}
        """
