I need to take my list from MAP and make them 4 decimal places

[MrMcNick]

My List that comes from my MAP function I need to get to 4 decimal places

'''
a = [5,4,6,8,9,12]
b = [3,5,3,7,4,10]
c = [4,7,7,4,10,14]
 
 
#Gets S List
hlist = map(add,a,b)
h2list = map(add,hlist,c)
twolist = [2,2,2,2,2,2]
s = map(truediv,h2list,twolist)
 
 
sqrtlist = [0.5,0.5,0.5,0.5,0.5,0.5]    
sa = map(sub,s,a) # (s-a)
sb = map(sub,s,b) # (s-b)
sc = map(sub,s,c) # (s-c)
sasb = map(mul,sa,sb) # (s-a)*(s-b)
sall = map(mul,sasb,sc) # (s-a)*(s-b)*(s-c)
x = map(mul,s,sall) # Multiplies inside by s
 
def square(x):
    return x**0.5
 
A = map(square,x)
 
 
AA = map(lambda x: x**0.5,x)
'''
"""
#OUTPUT
AA list
[6.0, 9.797958971132712, 8.94427190999916, 13.997767679169419, 17.984368212422698, 58.787753826796276]
 
[6.0, 8.0, 8.0, 9.5, 11.5, 18.0]

Thats my current code, minus some things. The numbers are correct I just need to to be rounded
