python - read string (IP addr) from file not the same as assign manually -


i want read ip address config file , use in socket udp transfer. 

import configparser # read config file , create constants cfgfile = 'omc-mt.cfg' config = configparser.configparser() config.sections() config.read(cfgfile) #print(config.sections()) addr = config['addr'] pc_ip = addr['osc_ip'] pc_port = int(addr['osc_port'])

in socket.bind 

pc_rxsock = socket.socket(socket.af_inet, socket.sock_dgram) pc_rxsock.bind((pc_ip, pc_port))

i'll error:

oserror: [errno 49] can't assign requested address

if compare read string , manually assigned find no differences:

pc_ip2 = '192.168.2.110' print (len(pc_ip)) print (len(pc_ip2))

at least same when print , @ same length. suppose has text encoding have no idea how fix it. text file saved utf-8 (editors says). use idle / python 3.4.2. cheers

content of omc-mt.cfg:

[addr] # ip address , port of osc device e.g. smartphone or tablet  osc_ip = 192.168.2.100 osc_port = 54047  # mastertone ip address mt_ip=192.168.2.200 mt_port=5001  # computer's ip , udp ports  # rx port must match tx port set in osc software pc_ip = 192.168.2.110 #pc_ip = 192.168.1.26 pc_port = 5005

consider these lines:

pc_ip = addr['osc_ip'] pc_port = int(addr['osc_port'])

i suppose want:

pc_ip = addr['pc_ip'] pc_port = int(addr['pc_port'])

bash - Performing variable substitution in a string -

i have string contains use of variable, , i'd substitute variable's value string. right best have is #!/bin/bash foo='$name; echo bar' name="the name" expanded="$(eval echo "$foo")" echo "$expanded" which has obvious defects: prints the name bar while i'd print the name; echo bar instead of eval can bash's regex matching bash's string replacement: foo='$name; echo bar' name="the name" [[ "$foo" =~ \$([[:alnum:]]+) ]] && s="${!bash_rematch[1]}" && expanded="${foo/\$${bash_rematch[1]}/$s}" echo "$expanded" name; echo bar
