I cannot find way to look at wallet.dat with pywallet. have not password. Can I see address with no password?

if i understood what you actually want to do, maybe you should;
- Try using bitcoin core to load that wallet.dat
- List all the addresses with the help of the console
- Then import the addresses to a Simplified Payment Verification(SPV) Wallet like Electrum or BreadWallet.
- There after you can just decide to make a watch only wallet

You could also try your luck Here (https://github.com/gurnec/btcrecover) if you want to try and recover that password. quite technical but give it a try.

There is a low chance to recover the password if you don't know some parts of your password and I think there is no chance that you can check your wallet addresses from a wallet.dat without a password.

So, if you follow the guide from BTCrecovery as posted above there is 1 to 5% chance that you can recover the password but you can increase this rate if you can remember most of your passwords or if you have the seed phrase you can recover the wallet without a password.

Follow the guide from here BTCRecovery guide (https://github.com/gurnec/btcrecover/blob/master/TUTORIAL.md#btcrecover-tutorial)

Edit: I just found a solution from here https://www.reddit.com/r/Bitcoin/comments/7v4ygv/recover_walletdat_without_password_possible/
Read few comments out there and you will find the solution to open this wallet.

Its encrypted if you need password, you can't answering your question.
You need to remember your password and if you can't, you can try brute-force it. To do that, you need to know some parts of password at least or big amount of luck. To tell you more, is it even worth hassle? How many bitcoins are in this wallet?

I think OP doesn't need a password if he just want to see the addresses in the wallet
he will only need the password when he wants to sign a transaction or extract private keys
--dumpwallet should give you output of all addresses and their encrypted private keys
check this post Re: What "--dumpwallet" do (pywallet) ... (https://bitcointalk.org/index.php?topic=1129050.msg11926691#msg11926691)
safety note: make multiple backup copies of your wallet.dat file and always work with a copy

perhaps he wants to see his addresses so that he can check their balances on block explorer
if he already know his wallet balance and/or addresses, most likely he will ask how to recover his bitcoin ;)
