Re format a python string after splitting

I have string like "week32_Aug_24_2016". I want to change this string like "week32_2016_Aug_24" I have tried this. 

str = "week32_Aug_24_2016"
wk = str.split('_')
newstr = wk[0]+" "+wk[3]+" "+wk[1]+" "+wk[2]

My expected output is "week32 2016 Aug 24". I already got that but I want to know is there any better way to do this. Suppose I have long string and no of split value is 10, then this is very long way. So I want to know a better way to arrange the split values. Thanks....

You can make use str.split() and format() as well:

str = "week32_Aug_24_2016"
wk = str.split('_')
newstr = "{} {} {} {}".format(wk[0], wk[3], wk[1], wk[2])

>>> import re
>>> string = "week32_Aug_24_2016"
>>> re.sub(r'_(.*)_(.*)_(.*)', r' \3 \1 \2', string)
'week32 2016 Aug 24'

str = "week32_Aug_24_2016"
wk = str.split('_')
i=0;
newstr="";
while(i<len(wk)):
    newstr=newstr+wk[i]+" "
    i=i+1
print newstr

Something like that. If you want to keep last string in the middle it can be done.

You can make use of both str.split() and str.join(), simply like this:

string = "week32_Aug_24_2016"
order = (0, 3, 1, 2)
parts = string.split('_')

new_string = ' '.join(parts[i] for i in order)

Also, note that I renamed your variable str to string to avoid shadowing built-in str class.
