Python for每秒仅循环一次Item [英] Python for loops only every second Item

问题描述

从来没有这样的问题，甚至不知道如何解决...

never had such a problem and do not know how to solve or even call it...

types = [105000, 105001, 105002, 105003, 105004, 105005, 105006, 105007]
for type in types:
    print type

仅打印

105000
105002
105004
105006

但我不知道为什么.

使用函数从类似的输入中生成数组

using a function to generate an array from input like

self.arrSplit(105000,105001,105002,105003,105004,105005,105006,105007)

功能:

    def arrSplit(self, arr):
        itms = []
        for it in arr.split(','):
            tt = it.split('-')
            if (len(tt) >= 2 and int(tt[0]) < int(tt[1])):
                for i in range(int(tt[0]), int(tt[1])+1):
                    itms.append(i)
            else:
                itms.append(int(tt[0]))
        return itms

要完成此操作，代码应如下所示(最小)

to complete this the code looks like this (its the minimum)

types = self.arrSplit(105000,105001,105002,105003,105004,105005,105006,105007)
print types
for type in types:
print type

打印:

[105000, 105001, 105002, 105003, 105004, 105005, 105006, 105007]
105000
105002
105004
105006

推荐答案

对于for循环，您应该使用以下代码:

For the for loop you should use this:

types = [105000, 105001, 105002, 105003, 105004, 105005, 105006, 105007]
for numbers in types:
    print numbers

这对我有用，但是我无法解释为什么它只打印偶数.

This worked for me, but I can't explain why it only printed evens.
