How to get a pretty print for my input file - python-3.x

Question

I have a file that contains data as shown in the Input file below. My program reads the config file, and writes section of this file as individual files. I read this file using python3 and pyyaml module. I get all the data I want, but when the data is written out to the output file, instead of the pretty-printed output, there are all these extra characters HOw can I get it pretty printed?
My ugly output:
"input {\n beats {\n port => 5044\n host => \"0.0.0.0\"\n tags => [\"output_beats\"\
]\n add_field => {\n \"[es][port]\" => 5044\n \"[es][type]\" => \"\
beats\" \n \"[es][subtype]\" => \"%{[#metadata][beat]}\"\n \"[#metadata][queue_prefix]\"\
\ => \"%{[#metadata][beat]}\"\n }\n }\n}\n"
Input file:
---
# Source: logstash/templates/configmap-receiver.yaml
apiVersion: v1
... removed for clarity
data:
100_beats_receiver_input_5044.conf : |
input {
beats {
port => 5044
host => "0.0.0.0"
tags => ["output_beats"]
add_field => {
"[es][port]" => 5044
"[es][type]" => "beats"
"[es][subtype]" => "%{[#metadata][beat]}"
"[#metadata][queue_prefix]" => "%{[#metadata][beat]}"
}
}
}
My code is pretty simple:
def read_and_process_yaml_file(filePath, outputDir):
"""Read file, return parsed python structure"""
print("About to read " + filePath)
with open(filePath,'r') as input_file:
yamlDocs = load_yaml(input_file)
for doc in yamlDocs:
print(yaml.dump(doc))
if (doc is not None) \
and (doc["kind"] is not None) and (doc["kind"].lower() == 'configmap') \
and ("test" not in doc["metadata"]["name"]):
print("doc.name=" + doc["metadata"]["name"])
for name, data in doc["data"].items():
print("name=" + name)
basename = name.split(".",1)
filePath = outputDir + "/" + basename[0] + ".yaml"
print(name + "|-")
#print(yaml.dump(data))
write_yaml_file(yaml.dump(data), filePath)

Answer 1

data is the string containing the desired output. If you do yaml.dump(data), you encode that string as a YAML scalar. Just do
write_yaml_file(data, filePath)
