Question

我知道之前曾多次问过这个问题，但是我无法弄清楚我的代码有什么问题以及如何解决它。

这是一个温度转换器

并显示错误：

import sys
import time
print('This program will convert different units of temperature.')
unit1 = input('What unit do you want to convert from?\nAnswer with the letter C, F or K.\n')
unit2 = input('And what unit to?\nUse the same ruling as the previous question.\n')
temp1 = input('What temperature do you want to convert?.\n')
temp2 = 0

if unit1 == ('C'):
    symbo1one = ('°C')

if unit1 == ('K'):
    symbolone = ('°K')

if unit1 == ('F'):
    symbolone = ('°F')

    unitname1 = ('Farhenheit')
    unitname2 = ('Kelvin')
if unit1 == unit2:
    temp2 = temp1

dp = ('To how many decimal places would you like your result given?')

print(('Original Temperature: ') + (str(temp1)) + (symbolone))
time.sleep(1)
print(('Converted Temperature: ') + (round(temp2, (dp))) + (symbol2))
time.sleep(10)
sys.exit()

我已经尽力了，并且我对编程还比较陌生，所以非常感谢您的帮助

Answer 1

两件事。在最后两行中，您忘记将input添加到dp中，并且无法将round值添加到字符串中，因此需要转换为字符串。

这将起作用

dp = int(input('To how many decimal places would you like your result given?'))
print(('Original Temperature: ') + (str(temp1)) + (symbolone))
time.sleep(1)
print(('Converted Temperature: ') + (str(round(temp2, (dp)))) + (symbol2))

Answer 2

dp = ('To how many decimal places would you like your result given?')

您是要用它来从用户那里得到一些东西吗？因为，如果这样做，它应该类似于：

dp = int(input('To how many decimal places would you like your result given?'))

'str'对象不能解释为整数（Python 3.8）
