Create GraphQL query in python

Question

I would like to modify this string:

query = """
    mutation { 
     productUpdate(input: {id: "gid://shopify/Product/463...03", title: "test", descriptionHtml: "Amazing product"}) {
       product {
         id
       }
       userErrors {
         field
         message
        }
      }
     }
  """

I'm trying to put a variable in the place of "test" and "Amazing product". Normally i would do this with f-strings, but because of the GraphQL brackets i cannot do this.

Does anyone have an idea on how to solve this problem?

Many thanks!

you can double up the curly braces to escape them:

my_title = "The Title"
my_description = "The description"

query = f"""
    mutation {{ 
     productUpdate(input: {{id: "gid://shopify/Product/463...03", title: "{my_title}", descriptionHtml: "{my_description}"}}) {{
       product {{
         id
       }}
       userErrors {{
         field
         message
        }}
      }}
     }}
  """

You can use the graphql-python/gql package. It supports variables.

While fstrings are great, in case of graphql queries you can just use below format.

query = """
    mutation { 
     productUpdate(input: {id: "gid://shopify/Product/463...03", title: "%s", descriptionHtml: "%s"}) {
       product {
         id
       }
       userErrors {
         field
         message
        }
      }
     }
  """ % ('test', 'Amazing Product')

print(query)
