yaml parse in python: SyntaxError: invalid syntax -


i want parse yaml file in python. hosts.yaml file below:

access:   host: abc     hosturl: url-for-abc     bearertoken: jjlhlj     expires: somedate   host: xyz     hosturl: url-for-xyz     bearertoken: kdsddh     expires: somedate

my python code parse yaml below:

import yaml  def parse():     open('hosts.yaml', 'r') hosts_file:         hosts = yaml.load(hosts_file)         host, val in  hosts["access"]["host"]:             print host             print host["hosturl"]             print host["bearertoken"]  parse()

i getting below error:

python parse_yaml.py traceback (most recent call last):   file "parse_yaml.py", line 19, in <module>     parse()   file "parse_yaml.py", line 13, in parse2     hosts = yaml.safe_load(hosts_file)   file "/usr/lib64/python2.7/site-packages/yaml/__init__.py", line 93, in safe_load     return load(stream, safeloader)   file "/usr/lib64/python2.7/site-packages/yaml/__init__.py", line 71, in load     return loader.get_single_data()   file "/usr/lib64/python2.7/site-packages/yaml/constructor.py", line 37, in get_single_data     node = self.get_single_node()   file "/usr/lib64/python2.7/site-packages/yaml/composer.py", line 36, in get_single_node     document = self.compose_document()   file "/usr/lib64/python2.7/site-packages/yaml/composer.py", line 55, in compose_document     node = self.compose_node(none, none)   file "/usr/lib64/python2.7/site-packages/yaml/composer.py", line 84, in compose_node     node = self.compose_mapping_node(anchor)   file "/usr/lib64/python2.7/site-packages/yaml/composer.py", line 133, in compose_mapping_node     item_value = self.compose_node(node, item_key)   file "/usr/lib64/python2.7/site-packages/yaml/composer.py", line 84, in compose_node     node = self.compose_mapping_node(anchor)   file "/usr/lib64/python2.7/site-packages/yaml/composer.py", line 127, in compose_mapping_node     while not self.check_event(mappingendevent):   file "/usr/lib64/python2.7/site-packages/yaml/parser.py", line 98, in check_event     self.current_event = self.state()   file "/usr/lib64/python2.7/site-packages/yaml/parser.py", line 428, in parse_block_mapping_key     if self.check_token(keytoken):   file "/usr/lib64/python2.7/site-packages/yaml/scanner.py", line 116, in check_token     self.fetch_more_tokens()   file "/usr/lib64/python2.7/site-packages/yaml/scanner.py", line 220, in fetch_more_tokens     return self.fetch_value()   file "/usr/lib64/python2.7/site-packages/yaml/scanner.py", line 576, in fetch_value     self.get_mark()) yaml.scanner.scannererror: mapping values not allowed here   in "hosts.yaml", line 3, column 12

i not able understand, if wrong yaml file structure of issue code. in advance.

you cannot have both string , object value of key. can either strings

access:   host: abc   host: xyz

or objects

access:   host:     hosturl: url-for-abc     bearertoken: jjlhlj     expires: somedate   host:     hosturl: url-for-xyz     bearertoken: kdsddh     expires: somedate

but not both

access:   host: abc     hosturl: url-for-abc     bearertoken: jjlhlj     expires: somedate   host: xyz     hosturl: url-for-xyz     bearertoken: kdsddh     expires: somedate

i suggest put name of host in name key in object

access:   host:     name: abc     hosturl: url-for-abc     bearertoken: jjlhlj     expires: somedate   host:     name: xyz     hosturl: url-for-xyz     bearertoken: kdsddh     expires: somedate

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
