2 variables should influence my calculations, but the calculations can't get past an if

Question

I want weave and length to determine 2 numbers in my equations. The last number in the equation is preset based on the weave entered.

Here is the code

# I want users to enter the weave and the functions to take that weeave 
# and calculate with with entered length and the predefined thickness of 
# the weave. 

weave = "hex nut"  # The weave determines the thickness of the braclet.
length = 6      # length determins that circumfrence of the wrist.
if weave == "cobra" or "fishtale" or "dragon tounge" or "braid":
    print(f"Your "  + (weave) + " braclet length inluding the buckle should be:")
    print(f"{length + .5 + (3.1459*.3125)}"+ " inches.") # length + .5 + (3.1459*.3125) 
                                                         # .3125 is the thickness of any the 
                                                         # weaves in the if statment

elif weave == "extreme weave":
    print(f"Your "  + (weave) + " braclet length inluding the buckle should be:")
    print(f"{length + .5 + (3.1459*.25)}"+ " inches.")

elif weave == "hex nut":
    print(f"Your "  + (weave) + " braclet length inluding the buckle should be:")
    print(f"{length + .5 + (3.1459*.44)}"+ " inches.")
    
elif weave == "blaze bar":
    print(f"Your "  + (weave) + " braclet length inluding the buckle should be:")
    print(f"{length + .5 + (3.1459*.38)}"+ " inches.")

elif weave == "king cobra or solomons dragon":
    print(f"Your "  + (weave) + " braclet length inluding the buckle should be:")
    print(f"{length + .5 + (3.1459*.5)}"+ " inches.")

else:
    print("Sorry, at this time " + (weave) + " is not in our Script.  Select another weave for your braclet.")
    print("Please contact Eric at elaunderville@gmail.com or ericlaunderville.tech")

I can get the weave to print but the calculations stop at the if statement
