Python 为什么这段代码好像卡在一个无限循环中？

我正在尝试创建条目（1000），我从名称开始。我想出了一些名字，我计划复制添加了数字0-9的条目，以创建更独特的名字。所以我在for循环中使用了for循环。无法将索引更改为字符串并将其添加到列表中项目的末尾

我考虑过增量，因为最近我一直在C++中编写很多代码，但是这不起作用，因为在使用Python的范围函数时不需要增加。我想改变循环的顺序

name = ['event', 'thing going on', 'happening', 'what everyones talkin', 'that thing', 'the game', 'the play', 'outside time', 'social time', 'going out', 'having fun']

我希望它能打印出

['event0'，'thinggoing1'，…'havingfun10']

谢谢大家!

使用一个新列表并附加到那里：

newName = []
for index in range(10): 
    for item in name:
        newName.append(item+str(index))
return newName

使用列表理解

• -方法将计数器添加到iterable，并以枚举对象的形式返回它

Ex.

name = ['event', 'thing going on', 'happening', 'what everyones talkin', 'that thing', 'the game', 'the play', 'outside time', 'social time', 'going out', 'having fun']
new_list = [x+str(index) for index,x in enumerate(name)]
print(new_list)

O/p:

['event0', 'thing going on1', 'happening2', 'what everyones talkin3', 'that thing4', 'the game5', 'the play6', 'outside time7', 'social time8', 'going out9', 'having fun10']

['event0', 'thing going on1', 'happening2', 'what everyones talkin3', 'that thing4', 'the game5', 'the play6', 'outside time7', 'social time8', 'going out9', 'having fun10']

它将按照您的预期工作：

name = ['event', 'thing going on', 'happening', 'what everyones talkin', 'that thing', 
'the game', 'the play', 'outside time', 'social time', 'going out', 'having fun']
for index in range(10): 
    name[index] = name[index]+str(index)
print (name)

输出：

['event0', 'thing going on1', 'happening2', 'what everyones talkin3', 'that thing4', 'the game5', 'the play6', 'outside time7', 'social time8', 'going out9', 'having fun10']

['event0', 'thing going on1', 'happening2', 'what everyones talkin3', 'that thing4', 'the game5', 'the play6', 'outside time7', 'social time8', 'going out9', 'having fun10']

每次运行循环时，都会向列表中添加更多元素。创建一个新的空列表并将元素附加到该列表中。这样，您的初始列表保持不变

内部for循环正在向数组追加新元素

你只需要

for index in range(10): 
    name[index] = name[index] + str(index)

现在，您的数组包含了预期的输出。顺便说一句，这会更改原始数组。如果希望它保持不变，请执行以下操作

newArray = []
for index in range(10): 
        newArray [index] = name[index] + str(index)

您正在将新项附加到要迭代的列表中。所以迭代将无限期地继续下去。
