本文介绍了Python FOR循环打印函数中的列表的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我还有一个问题,与我在这里有一样的问题 - > Python double FOR循环无线程 基本上,我希望第一个循环在这里列举列表中的每个学科,然后在里面打印功能,我希望打印每一个在该列表中的数字,所以它出现像8 - 4 - 5 - 7等。 -------------* 7))) ... 运行完整的代码使得大网格充满了这些东西,但不同的科目每一行。 (NTL here) ------------------------------------------ ------------------------------------------------- NTL |< generator object< genexpr>在0x0000000003404900> ---------------------------------------------- --------------------------------------------- 我有部分代码工作,所以每个列表编号都在另一个主题行中,所以我会有 NTL | 8.2 和下一行 ENT | 5.7 但是我希望所有这些数字都像 NTL | 8.2 - 5.7 - 等等 完成! -------------------------------------- -------------------------------------------------- --- NTL | 7.2 8.4 6.7 5.3 4.8 -------------------------------- -------------------------------------------------- --------- 解决方案生成器表达式中的code> str 将会打印 str 版本的生成器表达式,而不是像您期望的那样: >>> str((x对于范围(3)中的x))'<发生器对象< genexpr>在0xb624b93c>' 尝试如下所示: ($ {pre $ ) print(str) (item +|+ strs +\\\+(-------------* 7))) I have another question about somewhat the same problem as I had here ->Python double FOR loops without threadingBasically, I want the first for loop down here to enumerate over every school subject in a list, and then inside the print function, I want it to print every number that is in that list, so It comes out like 8 - 4 - 5 - 7 etc. for item in store: print(str(item + "|" + (str((cflist[i]) for i in range(3))) + "\n" + ("-------------" * 7)))...Running the complete code makes a big grid filled with these things, but differentsubjects each line. (NTL here)-------------------------------------------------------------------------------------------NTL|<generator object <genexpr> at 0x0000000003404900>-------------------------------------------------------------------------------------------I have had the code working partially, so that each list number was in another subject line, so I would have NTL|8.2 and the next line ENT|5.7 But I want all those numbers to display after each other like NTL|8.2 - 5.7 - etcEDIT:Done!-------------------------------------------------------------------------------------------NTL|7.2 8.4 6.7 5.3 4.8------------------------------------------------------------------------------------------- 解决方案 Using str on a generator expression will print str version of generator expression, not it's items as you expected:>>> str((x for x in range(3)))'<generator object <genexpr> at 0xb624b93c>'Try something like this:for item in store: strs = " ".join([cflist[i]) for i in range(3)]) print(str(item + "|" + strs + "\n" + ("-------------" * 7))) 这篇关于Python FOR循环打印函数中的列表的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
