Struggling to Parse Nested YAML with PyYAML - working with 'mapping' errors on Deeply Nested Structures
I'm trying to configure I'm trying to debug Hey everyone, I'm running into an issue that's driving me crazy..... I'm having trouble parsing a deeply nested YAML file using the PyYAML library in Python. The YAML structure looks like this: ```yaml parent: child1: - item1 - item2 child2: subchild: - item3 - item4 ``` When I try to load this YAML using `yaml.safe_load`, I'm working with the following behavior: `yaml.scanner.ScannerError: while parsing a block mapping`. The stack trace suggests that there's an scenario with the indentation, but I've double-checked the file and it seems correct. Here's the code snippet I'm using to parse the YAML: ```python import yaml with open('data.yaml', 'r') as file: data = yaml.safe_load(file) print(data) ``` I have confirmed that the YAML file is properly formatted and does not contain any hidden characters or incorrect line endings. I'm using PyYAML version 5.4.1, and I've tried both `yaml.load` and `yaml.safe_load`, but I keep working with the same scenario. Could the question be related to how PyYAML handles nested structures? I've also attempted to use a different YAML file with a simpler structure, and that works fine, which makes me think it’s specifically related to the depth of nesting in my current file. Any suggestions on how to troubleshoot or resolve this scenario would be greatly appreciated! What am I doing wrong? I'm coming from a different tech stack and learning Python. For context: I'm using Python on Ubuntu 20.04. Any help would be greatly appreciated! This issue appeared after updating to Python latest. Any pointers in the right direction?
