Question

我正在尝试创建一个简单的数组程序并打印出数组元素但在输入employee 2值之后立即收到错误：IndexError：list assignment index超出范围。

#Create constant for the number of employees.
SIZE = 3

#Create an array to hol the number of hours worked by each employee.
hours = [SIZE]

#Get the hours worked by employee 1.
hours[0] = int(input("Enter the hours worked by employee 1: "))

#Get the hours worked by employee 2.
hours[1] = int(input("Enter the hours worked by employee 2: "))

#Get the hours worked by employee 3.
hours[2] = int(input("Enter the hours worked by employee 3: "))

#Display the values entered.
print("The hours you entered are:")
print(hours[0])
print(hours[1])
print(hours[2])

Answer 1

您似乎对数组如何在Python中工作有错误的想法。基本上当你输入

时你正在做什么

#Create constant for the number of employees.
SIZE = 3

#Create an array to hol the number of hours worked by each employee.
hours = [SIZE]

使用一个元素创建一个值为3

的数组

hours = [3]

Answer 2

Python没有文字数组：它有列表。 hours = [SIZE]不会创建包含3个元素的列表：它会创建一个包含1个元素的列表。您应该使用append()将项添加到列表中，而不是索引到数组的末尾。

正确的代码看起来像这样将元素添加到列表中：

hours.append(int(input("Enter the hours worked by employee 1: ")))
hours.append(int(input("Enter the hours worked by employee 2: ")))
hours.append(int(input("Enter the hours worked by employee 3: ")))

从评论中，您似乎正在学习伪代码教科书中的代码：这太棒了。请记住，虽然伪代码或类似C语言的某些惯例在其他编程语言中可能有所不同。例如，在C中，这声明了一个名为x的50个字符的数组。

char x[50];

在Python中，您不能使用相同的语法。祝你好运。
