Python best practice - should I initialize variables with values?

I haven't found precise answer to the question (Python).

Is a good practice to intialize variables at the beggining or should that be done later? And what type of the value should I give them at the beginning?

example:

variable_str = None  #  Should I give None to them all?
variable_int = None  #  
variable_float = 0.0 # Should I give float for type float?

# Code.......
# I will use that variables later on,....

Some say it is a good practice, but I am confused which data type should be used? Python is dynamically typed, but nevertheless what is the best practice?

There's no need to mention variables before you first need to give them an actual useful value. Don't put dummy values at the top of your program.
