Repeat string to certain length

What is an efficient way to repeat a string to a certain length? Eg: repeat('abc', 7) -> 'abcabca'

Here is my current code:

def repeat(string, length):
    cur, old = 1, string
    while len(string) < length:
        string += old[cur-1]
        cur = (cur+1)%len(old)
    return string

Is there a better (more pythonic) way to do this? Maybe using list comprehension?

This is pretty pythonic:

newstring = 'abc'*5
print newstring[0:6]

def extended_string (word, length) :

    extra_long_word = word * (length//len(word) + 1)
    required_string = extra_long_word[:length]
    return required_string

print(extended_string("abc", 7))

c = s.count('a')    
div=n//len(s)    
if n%len(s)==0:
    c= c*div
else:
    m = n%len(s)
    c = c*div+s[:m].count('a')
print(c)

Currently print(f"{'abc'*7}") generates:

abcabcabcabcabcabcabc
