Hello Team,
I have a sample code that runs through the list of dictionary and return a
dictionary if the search value matched
*Sample Program:*
#!/usr/bin/python
def return_matched_owner(dict_list,search_block):
"""Accepts a list of dictionary with owners and returns a dict if there
is a match"""
try:
x = next(item for item in dict_list if item.get("Block") ==
search_block)
except StopIteration:
return False
return x
def main():
dict_list = [{'real_owner': '1:0070', 'fake_owner': '121212aaa',
'Block': '121212121'},
{'real_owner': '1:0170', 'fake_owner': 'aaabbbb', 'Block':
'21115674'},
{'real_owner': '1:0120', 'fake_owner': 'accccb', 'Block':
'31115674'}]
x = return_matched_owner(dict_list,'31115674')
print x
if not x:
assert False, "Error while getting owner"
print "\n Matching owner found \n"
if __name__ == '__main__':
main()
*Sample o/p:*
yy-1# python stack1.py
{'real_owner': '1:0120', 'fake_owner': 'accccb', 'Block': '31115674'}
Matching owner found
Couple of question here :
1. Any better suggestion to optimize the code and any other
observations around use of assert, generators and are exception handled
correctly in return_matched_owner()
Regards,
Ganesh
