爲什麼我會收到「回溯（最近一次通話最後一次）：」錯誤？

Question

我很抱歉問，但我找不到爲什麼我得到這個錯誤，特別是在程序運行後。

的誤差修改是準確的：

>>> 
Welcome! This program will convert measures for you. 
Select operation. 
1.Miles to Kilometers 
2.Fahrenheit to Celsius 
3.Gallons to liters 
4.Pounds to kilograms 
5.Inches to centimeters 
Enter your choice by number: 1

我不知道什麼是錯......任何人都可以幫助我嗎？ 謝謝！

在文件的開始處，您將raw_input設置爲0.不要這樣做，因爲它會修改內置的raw_input()函數。因此，每當您撥打raw_input()時，實質上都會調用​​，這會引發錯誤。要刪除錯誤，請刪除代碼的第一行：

M = 1.6 
# Miles to Kilometers

我不知道你使用的是哪個版本的Python，但我想這在Python 3，並提出了一些變化，它看起來像它的工作原理。 raw_input函數似乎是這裏的問題。我將所有raw_input函數改爲「input（）」，並且我還對打印進行了細微的更改以與Python 3兼容。AJ Uppal說他不應該命名同名的變量和函數。看到這裏供參考：

TypeError: 'int' object is not callable

我的Python 3代碼如下：

# https://stackoverflow.com/questions/27097039/why-am-i-getting-a-traceback-most-recent-call-last-error 

raw_input = 0 
M = 1.6 
# Miles to Kilometers 
# Celsius Celsius = (var1 - 32) * 5/9 
# Gallons to liters Gallons = 3.6 
# Pounds to kilograms Pounds = 0.45

我在你的代碼注意到了一個小錯誤也是如此。這個功能應該理想地將磅轉換爲千克，但它看起來像打印時，它正在打印「釐米」而不是千克。

def convertPK(): 
    input_P = float(input(("Pounds: "))) 
    P_conv = input_P * 0.45 
    # Printing error in the line below 
    print("Centimeters: {P_conv}\n") 
    restart = str(input("Do you wish to make another conversion? [y]Yes or [n]no: ")) 
    if restart == 'y': 
     main() 
    elif restart == 'n': 
     end() 
    else: 
     print ("I didn't quite understand that answer. Terminating.") 
     main() 

我希望這有助於。
