记录下总是码错的地方 for key,value in final_table:#final_table is a dict 然后报错 File "./count_co_Mty_read_nu.py", line 190, in count_haplotype_read_number for key,value in final_table: ValueError: too many values to unpack (expected 2) 字典是的迭代元素是字典的key值,多加了一…
先感谢[ValueError: too many values to unpack](http://leonzhan.iteye.com/blog/1720315)系统出现异常:打开太多值(预期2)这种错误是指一个tuple值赋给一个tuple变量时,变量个数不够.如:a,b = (1,2,3)for example: if ditc_a is dict, following code will get this errorfor key, value in ditc_a: ... Correc…
现象是: python easy.py train test 输出: Scaling training data...WARNING: original #nonzeros 100389 new #nonzeros 9983948Use -l 0 if many original feature values are zerosCross validation...Traceback (most recent call last): File "easy.py", line 61, i…
看完18章以后,发现第一个练习中,使用了*args读取全部的的输入参数作为一个元组,但是在他的练习中只给了两个变量去赋值,当用户不清楚这个函数的定义时,就可能会给出过多的变量进这个函数,那么就会出现如下错误: ValueError: too many values to unpack 也就是所谓的解包错误,给出的值太多了. 那么为了杜绝这种情况,我取巧解决了下.就是我把元组改变成一个列表,然后补了2位进去. 如果他给的变量少了也没关系,我能补齐.可能太搓了,以后有好的思路再来补齐. def pr…
12.1 Tuples are immutable(元组是不可变的)A tuple is a sequence of values. The values can be any type, and they are indexed by integers, so in that respect tuples are a lot like lists. The important difference is that tuples are immutable.Syntactically, a tu…
