How to put a string of json string representation into a json string: AWS eventbridge

I hope the title makes sense. What I am trying to do is create the AWS cdk code to have an AWS eventbridge rule trigger a lambda function with static input. What the input needs to look like is this

"""{
  "resource": "/{proxy+}",
  "path": "/jobs/sendRepoJob",
  "httpMethod": "POST",
  "requestContext": "{}",
  "queryStringParameters": null,
  "multiValueQueryStringParameters": null,
  "pathParameters": null,
  "stageVariables": null,
  "body": "{\"Configs\":{\"_url\":\"<some_url>",\"name\":\"<some_name>\"},\"Configs2\":{\"_url\":\"<some_url>",\"name\":\"<some_name>\"}}"
  "isBase64Encoded": null
}"""

Basically, I need the json string as the body in the static input for the eventbridge rule. However, when I try to create the rule with AWS CDK, the events.CfnRule.TargetProperty object takes a json string as input as seen from the documentation https://docs.aws.amazon.com/cdk/api/v1/python/aws_cdk.aws_events/CfnRule.html#aws_cdk.aws_events.CfnRule.TargetProperty

My code for creating event in AWS CDK is shown below.

rule = events.CfnRule(self,
    "InvokeApiRule",
    description="test",
    schedule_expression="rate(2 minutes)",
    state="ENABLED",
    role_arn=role.role_arn,
    targets=[events.CfnRule.TargetProperty(
        arn="<lambda_arn>",
        id="<someID>",
        dead_letter_config=events.CfnRule.DeadLetterConfigProperty(
            arn="<dlq_arn>"
        ),
        input = tmp_input
)])

When I try making the json string, in the script for "tmp_input", it automatically converts it to json when creating the stack. I need it to be a string, and stay a string as I showed above.

Anyone know how to do this?

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...

Sorting large arrays of big numeric stings

I was solving bigSorting() problem from hackerrank: Consider an array of numeric strings where each string is a positive number with anywhere from to digits. Sort the array's elements in non-decreasing, or ascending order of their integer values and return the sorted array. I know it works as follows: def bigSorting(unsorted): return sorted(unsorted, key=int) But I didnt guess this approach earlier. Initially I tried below: def bigSorting(unsorted): int_unsorted = [int(i) for i in unsorted] int_sorted = sorted(int_unsorted) return [str(i) for i in int_sorted] However, for some of the test cases, it was showing time limit exceeded. Why is it so? PS: I dont know exactly what those test cases were as hacker rank does not reveal all test cases. source https://stackoverflow.com/questions/73007397/sorting-large-arrays-of-big-numeric-stings
