Python 这个代码需要更正。I'；我无法在此程序中运行elif部件

我无法访问

elif

部件：

total = input('What is the total amount for your online shopping?')
country = input('Shipping within the US or Canada?')

if country == "US":
    if total <= "50":
        print("Shipping Costs $6.00")
    elif total <= "100":
        print("Shipping Costs $9.00")
    elif total <= "150":
        print("Shipping Costs $12.00")

    else:
        print("FREE")

if country == "Canada":
    if total <= "50":
        print("Shipping Costs $8.00")
    elif total <= "100":
        print("Shipping Costs $12.00")
    elif total <= "150":
        print("Shipping Costs $15.00")
    else:
        print("FREE")

total=input（'您网上购物的总金额是多少？'）
国家=输入（“在美国或加拿大境内运输”）
如果国家=“美国”：
如果total实际上，您可以使用int（“50”）将“50”从字符串转换为整数50

total = input('What is the total amount for your online shopping?')

python输入默认为字符串数据类型。您必须转换为int才能进行比较

total = int(input('What is the total amount for your online shopping?'))

更新工作代码：

total = int(input('What is the total amount for your online shopping?'))
country = input('Shipping within the US or Canada?')

if country == "US":
    if total <= 50:
        print("Shipping Costs $6.00")
    elif total <= 100:
        print("Shipping Costs $9.00")
    elif total <= 150:
        print("Shipping Costs $12.00")

    else:
        print("FREE")

if country == "Canada":
    if total <= 50:
        print("Shipping Costs $8.00")
    elif total <= 100:
        print("Shipping Costs $12.00")
    elif total <= 150:
        print("Shipping Costs $15.00")
    else:
        print("FREE")

total=int（输入（'网上购物的总金额是多少？'））
国家=输入（“在美国或加拿大境内运输”）
如果国家=“美国”：
如果total您正在比较字符串。使用
total=int（input（…）
将输入更改为整数，并将其与数字而不是字符串进行比较：
如果total您在比较整数时比较字符串，则表示您在比较
ASCII
值。

请参见以下代码段：

total = "120"
if total <= "50":
    print("yes")

total=“120”
if total if total这里的“50”是字符串。改为总数
