当询问他们的储蓄和存款时，我试图在用户输入中添加一个美元符号（“$”）。在我的脚本结束时，我正在创建一个包含所有信息的文本文件，但我希望在创建文件时数字前面有符号。

savings =  int(input("How much money do you have in your savings: ")
deposits = int(input("How much money do you put in deposits: ") 

from tabulate import tabulate
table = tabulate([["Name", "Last", "Age", "Company", "Hourly Rate", "Occupation", "Savings", "Deposits"],
[(name), (last_name), (age), (company), (hourly_rate), (occupation), (savings, + "$"), (deposits)]], headers = "firstrow")

我已将 +"$" 添加到 Savings 变量中，因为我认为这会起作用，但后来我会收到此错误：

TypeError: bad operand type for unary +: 'str'

所以总而言之，即使创建了文本文件，我也只希望它具有美元符号，因为这是它现在看起来的示例：

储蓄存款

9000 900 <----缺少美元符号

我希望这是有道理的。谢谢你。

看看你是否会使用int然后你不能将钱与美元符号连接起来，因为'$'是一个字符串。你可以这样做：

# Trying to make it have a special character when file is printed such as "$" Example: $2600
savings = '$' + input("How much money do you have in your savings: ")
deposits = '$' + input("How much money do you put in deposits: ")

When you print the variables, you can type cast them into string and append $ at the start.

print("$"+str(savings))
print("$"+str(deposits))

好吧，这很容易

对于 Python3，您可以简单地使用F Strings

savings = int(input("How much money do you have in your savings: "))
deposits = int(input("How much money do you put in deposits: "))
print(f"₹ {savings}")
print(f"₹ {deposits}")

您可以使用该%标志。
% 符号后跟一个指向数据类型的字符。如果是整数，请使用 d。

%s -> String
$d -> Int
%f -> Float

savings = int(input("How much money do you have in your savings: "))
deposits = int(input("How much money do you put in deposits: "))

savings = "$%d" % savings
deposits = "$%d" % deposits

你可以使用f-strings.

如果您只想$在前面打印，

savings = int(input("How much money do you have in your savings: "))
deposits = int(input("How much money do you put in deposits: "))

print(f'Savings: ${savings}')
print(f'Deposits: ${deposits}')

Sample Output:

Savings: $51
Deposits: $25

如果你想保存savingsand前面deposits有一个，那么$

savings = '$' + input("How much money do you have in your savings: ")
deposits = '$'+ input("How much money do you put in deposits: ")

savings并且deposits现在将是字符串而不是int。
