Write the Python code to generate the terms of the following series up to n terms (n is user input) using a for loop and find the sum of the terms of the series [you should print the terms of the series exactly as shown below]:
S = 1/(4*5) – 1/(6*10) + 1/(8*20) – 1/(10*40) … up to n terms

N=int(input("Enter Terms : "))
p=S =""
n=4
d=5
for i in range(1,N+1):
    if i==1:
        p=p + "1/(" + str(n) + "*" + str(d) + ")"
    elif i%2==0:
        p=p + "-1/(" + str(n) + "*" + str(d) + ")"
    else:
        p=p + "+1/(" + str(n) + "*" + str(d) + ")"
    n=n+2
    d=d*2
print(p)
