print IP address with interface name

I want to show the IP address like below

lo : 127.0.0.1 
eth0 : 192.168.5.123
eth1 : 192.172.0.212
wlan0 : 10.1.0.124

I'm able to print all IP address by ifconfig | awk '/inet addr/{print substr($2,6)}'. But it is only printing the IPs. Every system have their own interface names and addresses. So my script has to show their interfaces with respect to IP addresses.
