不确定如何从字符串中删除空白

Question

current_price = int(input())
last_months_price = int(input())

print("This house is $" + str(current_price), '.', "The change is $" +
str(current_price - last_months_price) + " since last month.")
print("The estimated monthly mortgage is ${:.2f}".format((current_price * 0.051) / 12), '.')

这产生：

This house is $200000 . The change is $-10000 since last month.
The estimated monthly mortgage is $850.00 .

我不确定如何去除"$200000"和"$850.00"之后的空白。我不完全理解strip()命令，但从我读到的内容来看，它对这个问题没有帮助。

Answer 1

您可以为print提供一个附加参数：sep，如下所示：

print("This house is $" + str(current_price), '.', "The change is $" +
str(current_price - last_months_price) + " since last month.", sep='')

因为默认值是逗号后面的空白。

Answer 2

也许可以尝试f字符串注入

print(f"This house is ${current_price}. The change is ${current_price - last_months_price} since last month.")

f-string(格式化字符串(提供了一种使用最小语法将表达式嵌入字符串文本中的方法。这是一种连接字符串的简化方法，不必显式调用str来格式化字符串以外的数据类型。

正如@Andreas在下面指出的，您也可以将sep=''传递给print，但这需要您将其他字符串与格式正确的空格连接起来。

Answer 3

print("This house is $" + str(current_price), '.',' ' "The change is $" +
str(current_price - last_months_price) + " since last month.", sep='')
print("The estimated monthly mortgage is ${:.2f}"'.'.format((current_price * 0.051) / 12))
