编写 EMI 计算器程序

# input the loan amount
loan = int(input("enter the loan amount: "))

# input the loan tenure in years and convert to months
tenure_year = int(input("enter the loan tenure in years: "))
tenure_month = tenure_year * 12  # convert years to months
print("loan tenure in months:", tenure_month)

# input the interest rate per year and convert to monthly interest rate
interest_year = float(input("enter the interest per year: "))
interest_month = interest_year / 12 / 100  # convert annual interest rate to monthly decimal rate
print("interest per month in percentage:", interest_month)

# calculate emi using the formula
emi = loan * (interest_month * (1 + interest_month) ** tenure_month) / ((1 + interest_month) ** tenure_month - 1)

# display the calculated emi, rounded to 2 decimal places
print("emi:", round(emi, 2))
