YAML - 多次打印字符串

Question

Is there an easy way in YAML to print a string a number of times?

for example in Python

print('String' * 500)

Can't get the syntax working in YAML

Answer 1

You can use below to print the string say 50 times:

- name: Print 50 times
  hosts: localhost
  tasks:
      - name: with file
        debug: msg="This is my loop"
        with_sequence: count=50

Answer 2

YAML ("YAML Ain't Markup Language") is a human-readable data-serialization language. It is commonly used for configuration files and in applications where data is being stored or transmitted.

Its not a programming language. So that I think you can solve your problem with Python's yaml library.

1. load YAM file as Python object
2. Update the value here ('String' * 500)
3. Dump Python object to YAML file.
