Also thanks for the snippet you provided. This is a really helpful for me as a beginner. How did you know which module is the correct one for this task? Did you just run something similar like
Code:
grep -R -i 'get_balance'
No, i found out the correct module by checking pycoin documentation[1]. Since you mentioned get_balance function, i use that as keyword on search bar[2]. One of the search result lead to module called BlockcypherProvider[3]. Afterwards, i simply try initialize module BlockcypherProvider and then use get_balance function.

[3] https://pycoin.readthedocs.io/en/latest/source/pycoin.services.html?highlight=get_balance#pycoin.services.blockcypher.BlockcypherProvider.get_balance
If documentation isn't exist, usually i'd look for example on their GitHub repository or read the source code directly.
Please look over it and tell me where the errors are or how you suggest to optimize for better performance.
Code:
#!/usr/bin/python3
import sys
from pycoin.services.blockcypher import BlockcypherProvider
args = sys.argv
filepath = args[1]
bp = BlockcypherProvider()
with open(filepath, 'r') as f:
addresslist = f.readlines()
addresslist = [a.strip('\n') for a in addresslist]
# do something with address list here
print(addresslist)
# retrieve and output balance and tx info of each address listed in provided address.lst
# with a line separator (horizontal line or similar)
#result = bp.get_balance(addresslist)
for details in addresslist:
result = bp.get_balance(details)
print(result)
print('―' * 40) # U+2015, Horizontal Bar, 40 times
import sys
from pycoin.services.blockcypher import BlockcypherProvider
args = sys.argv
filepath = args[1]
bp = BlockcypherProvider()
with open(filepath, 'r') as f:
addresslist = f.readlines()
addresslist = [a.strip('\n') for a in addresslist]
# do something with address list here
print(addresslist)
# retrieve and output balance and tx info of each address listed in provided address.lst
# with a line separator (horizontal line or similar)
#result = bp.get_balance(addresslist)
for details in addresslist:
result = bp.get_balance(details)
print(result)
print('―' * 40) # U+2015, Horizontal Bar, 40 times
At a glance, i didn't see any error. But personally i'd replcae for details in addresslist: with for address in addresslist: for better readability. I don't know much about performance (since i use Python for small/light stuff), but people usually advice to use Python Async feature.
but thanks to your grateful suggestions certainly I will succeed some day. Will dig further into Codecademy, W3schools and learnpython
