Joining strings in Python

Question

archive= ['Frederick the Great',
          'Ivan the Terrible',
          'maurice Of Nassau',
          'Napoleon BONAPARTE']

   n=[]
   n2=[]
   n3[]

    for line in archive:
        n.append(line)

    for x in n :
        lw = x.lower()
        for i in lw.split() :
            n2.append(i)

    for i in n2 :

        if i == 'of' or i == 'the' :
            i=i.lower()
            n3.append(i)

        else: 
            i=i.capitalize()
            n3.append(i) 

    print(n3)

this code prints the names as strings, how could .join() be used to do that or using some other method making so that the output would be words in the names are capitalized, the and of are in lowercase and together. PS:Still new to programming sorry for any mistakes in the formulation of the question.

What is your desired output? And what's actually in archive? right now it's probably a syntax error — Taku

Your archive section doesn't have quotes or commas. Make sure your code runs before posting an example. — T. Arboreus

n, n2 and n3 will cause errors because they are not initialized. For example, n = [] — somesingsomsing

the out put should be something like 'Frederick the Great', 'Ivan the Terrible','Maurice of Nassau','Napoleon Bonaparte' However i'm getting 'Ivan','the',Terrible','Maurice','of','Nassau' — guipleite

Expecting there are no quotations or punctuations, you can do as follows

archive = ['Frederick the Great',
          'Ivan the Terrible',
          'maurice Of Nassau',
          'Napoleon BONAPARTE']

reformated = [
    ' '.join(word.capitalize()
             if word not in ('the', 'of')
             else word
             for word in line.lower().split())
    for line in archive
]

['Frederick the Great',
 'Ivan the Terrible',
 'Maurice of Nassau',
 'Napoleon Bonaparte']

I write the short function to do capitalize the given string. You can use map in order to apply to all list of string in the list.

archive= ['Frederick the Great',
          'Ivan the Terrible',
          'maurice Of Nassau',
          'Napoleon BONAPARTE']

def capitalize_phrase(text):
    s_capitalize = []
    for s in text.split(' '):
        if s.lower() in ['the', 'of']:
            s_capitalize.append(s.lower())
        else:
            s_capitalize.append(s.capitalize())
    return ' '.join(s_capitalize)

print(list(map(capitalize_phrase, archive)))

Another solution:

archive= [
    'Frederick the Great',
    'Ivan the Terrible',
    'maurice Of Nassau',
    'Napoleon BONAPARTE'
]

lines = []
for line in archive:
    line = line.lower().split()
    for i, word in enumerate(line):
        if word in ('of', 'the'):
            continue
        line[i] = word.capitalize()
    lines.append(' '.join(line))

print lines

The advantage of this solution is that it lowers the line in 1 shot, and just continues to the next word when the word if 'of' or 'the', which saves processing cycles.
