You are not selecting multiple indexes with PriceList[0][1][2][3][4][5][6] , instead each [] is going into a sub index.

Try this

PizzaChange=float(input("What would you like the new price for all standard pizzas to be? "))      
PriceList[0:7]=[PizzaChange]*7  
PriceList[7:11]=[PizzaChange+3]*4

PriceList 0  is a float  PriceList 0  1  is trying to access the first element of a float   Instead  do  PriceList 0    PriceList 1       code omitted      PriceList 6    PizzaChange   or   PriceList 0 7     PizzaChange  7

PriceList 0  1  2  3  4  5  6    This says  go to the 1st item of my collection PriceList   That thing is a collection  get its 2nd item   That thing is a collection  get its 3rd     Instead  you want slicing   PriceList  7     PizzaChange  7

It looks like you are trying to set elements 0 through 11 of PriceList to new values  The syntax would usually look like this   prompt    What would you like the new price for all standard pizzas to be    PizzaChange   float input prompt   for i in  0  1  2  3  4  5  6   PriceList i    PizzaChange for i in  7  8  9  10  11   PriceList i    PizzaChange   3   If they are always consecutive ranges  then it s even simpler to write   prompt    What would you like the new price for all standard pizzas to be    PizzaChange   float input prompt   for i in range 0  7   PriceList i    PizzaChange for i in range 7  12   PriceList i    PizzaChange   3   For reference  PriceList 0  1  2  3  4  5  6  refers to  Element 6 of element 5 of element 4 of element 3 of element 2 of element 1 of element 0 of PriceList  Put another way  it s the same as       PriceList 0   1   2   3   4   5   6
