在数字中添加逗号

导入区域设置

def format_currency（amount，grouping=True）：返回locale.format_string（“%.2f”，amount，group=True）

def main（）：locale.setlocale（locale.LC_ALL，“”）

print("Welcome to the Sales Receipt Generator\n")


name = input("Please enter your name: ").title()

packages = int(input("Please enter the number of packages: "))

if packages < 10:
    discount_percent = 0
elif packages >= 10 and packages <= 19:
    discount_percent = .10
elif packages >= 20 and packages <= 49:
    discount_percent = .20
elif packages >= 50 and packages <= 99:
    discount_percent = .30
else:
    discount_percent = .40

subtotal = packages * 100
discount_amount = subtotal * discount_percent
total_price = subtotal - discount_amount

print("\nSales Receipt ")
print("Name: ", name)
print("Quantity of Packages: ", locale.format_string("%d", (packages,), grouping=True))
print("Discount Percentage: {}% ".format(int(discount_percent *100.00)))
print("Sub Total: ", locale.format_string("%d", int(subtotal), grouping=True))
print("Discount Amount: ", locale.format_string("%.2f", discount_amount, grouping=True))
print("Total Price: $", locale.format_string("%.2f", total_price, grouping=True))

如果名称==“main”：main（）

我试图让小计等于一个带逗号的数字（例如：1500），但它一直是1500。我也试图让总价等于1350.00美元，但一直得到1350.00美元而没有昏迷。我怎么解决这个问题？
