如何将符号添加到用户输入(Python)

Amar Mujak • 3 年前 • 1394 次点击

我试图在用户输入的内容中添加一个美元符号($),当它询问他们的储蓄和存款时。在脚本的末尾,我创建了一个包含所有信息的文本文件,但我希望在创建文件时,数字前面有一个符号。

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")

我在savings变量中添加了+“$”,因为我认为这会起作用,但随后会出现以下错误:

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

总之,我只希望它在创建文本文件时也有美元符号,因为这是它现在的样子:

储蓄存款

9000 900<----丢失的美元符号

我希望这是有道理的。非常感谢。

你可以使用 % 签名
%符号后面跟着一个指向数据类型的字符。如果是整数,则使用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

这很容易做到

对于Python3,您只需使用 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"â¹ {savings}")
print(f"â¹ {deposits}")

你可以用 f-strings .

如果你只是想用 $ 那么在前面,

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

如果你想拯救世界 savings 和 deposits 用一个 $ 那么在前面

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

节省物 和 存款 现在将是字符串而不是 int .

打印变量时,可以将它们转换为字符串,并在开头追加$。

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

看看你是否会使用 int 然后不能将货币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: ")
