将文本列表格式化为列

我正在尝试将字符串值列表输出为 2 列格式。将字符串列表制作为“普通文本”的标准方法是使用字符串连接方法。但是，它只需要 2 个参数，因此我只能使用“\n”创建一个列。我认为尝试创建一个循环，只需在列之间添加一个选项卡就可以做到这一点，但逻辑无法正常工作。

我找到了一个活动状态页面 http://code.activestate.com/recipes/302380/这是一个相当复杂的方法，但这是 4 年前的事了。现在有没有简单的方法可以做到这一点？

Edit这是我想要使用的列表。

skills_defs = ["ACM:Aircraft Mechanic", "BC:Body Combat", "BIO:Biology",
    "CBE:Combat Engineer", "CHM:Chemistry", "CMP:Computers", 
    "CRM:Combat Rifeman", "CVE:Civil Engineer", "DIS:Disguise",
    "ELC:Electronics","EQ:Equestrian", "FO:Forward Observer",
    "FOR:Forage", "FRG:Forgery", "FRM:Farming", "FSH:Fishing",
    "GEO:Geology", "GS:Gunsmith", "HW:Heavy Weapons", "IF:Indirect Fire",
    "INS:Instruction", "INT:Interrogation", "JP:Jet Pilot", "LB:Longbow",
    "LAP:Light Aircraft Pilot", "LCG:Large Caliber Gun", "LNG:Language",
    "LP:Lockpick", "MC:Melee Combat", "MCY:Motorcycle", "MEC:Mechanic",
    "MED:Medical", "MET:Meterology", "MNE:Mining Engineer",
    "MTL:Metallurgy", "MTN:Mountaineering", "NWH:Nuclear Warhead",
    "PAR:Parachute", "PST:Pistol", "RCN:Recon", "RWP:Rotary Wing Pilot",
    "SBH:Small Boat Handling","SCD:Scuba Diving", "SCR:Scrounging",
    "SWM:Swimming", "TW:Thrown Weapon", "TVD:Tracked Vehicle Driver",
    "WVD:Wheeled Vehicle Driver"]

我只想将此列表输出为简单的 2 列格式以减少空间。理想情况下，列之间应该有标准的空间量，但我可以使用它。

ACM:Aircraft Mechanic        BC:Body Combat 
BIO:Biology         CBE:Combat Engineer

两列由制表符分隔，连接成行。在看迭代工具对于迭代器等价物，以实现节省空间的解决方案。

import string
def fmtpairs(mylist):
    pairs = zip(mylist[::2],mylist[1::2])
    return '\n'.join('\t'.join(i) for i in pairs)

print fmtpairs(list(string.ascii_uppercase))

A   B
C   D
E   F
G   H
I   J
...

哎呀...被S.Lott抓住了（谢谢）。

更通用的解决方案可以处理任意数量的列和奇数列表。稍作修改自S.lott https://stackoverflow.com/questions/171662/formatting-a-list-of-text-into-columns#173823，使用发电机来节省空间。

def fmtcols(mylist, cols):
    lines = ("\t".join(mylist[i:i+cols]) for i in xrange(0,len(mylist),cols))
    return '\n'.join(lines)
