# Compound interest
def compute_CI(principal, interestRate, period):
    # compound interest formula
    ci = principal * (pow((1 + interestRate/100), period))
    return ci

# Taking inputs from user
principal = 1000
interestRate = 5
period = 10

# Calculate compound interest
ci = compute_CI(principal, interestRate, period)

# Print the resultant value of compound interest
print("Compound interest is", ci)
