do replacement evenly

[oyster]

here is what I get
[code]
import re
reSplitObj=re.compile('([ \t]*)|([^ \t]*)')
def evenReplace(aStr, length):
    aStr=aStr.rstrip()
    tmp=reSplitObj.split(aStr)
    tmp=[i for i in tmp if i not in ['', None]]
    lenStr=[[0, len(i)][i.strip()!=''] for i in tmp]
    lenSpc=[[0, len(i)][i.strip()==''] for i in tmp]
    while sum(lenStr)+sum(lenSpc)>length:
        if sum(lenSpc):
            lenSpc[lenSpc.index(max(lenSpc))]-=1
        else:
            break
    newSpc=[' '*i for i in lenSpc]
    _=[]
    for i in range(len(tmp)):
        item=tmp[i]
        if item.strip()!='':
            _.append(item+newSpc[i])
        else:
            _.append(newSpc[i])

    return ''.join(_)

if __name__=='__main__':
    a='hello world'
    b= evenReplace(a, 5)
    print 'a="%s", len=%0i' %(a, len(a))
    print 'b="%s", len=%0i' %(b, len(b))
    print

    a='hello    world   yeah    event    even '
    b= evenReplace(a, 27)
    print 'a="%s", len=%0i' %(a, len(a))
    print 'b="%s", len=%0i' %(b, len(b))
    print
