Pre-minted tokens
The FA2 base classes accept an initial list of token metadata (or a single value for FA2SingleAsset) and an initial ledger. This gives you the ability to have pre-mint tokens in the contract storage at origination time.
See base classes for more info about the ledger value.
Examples

python
alice = sp.test_account("Alice")
tok0_md = make_metadata(name="Token Zero", decimals=1, symbol="Tok0")
tok1_md = make_metadata(name="Token One", decimals=1, symbol="Tok1")
tok2_md = make_metadata(name="Token Two", decimals=1, symbol="Tok2")
