for i in range 11       string    string 0   format i    What you did  range 1 10   is    a TypeError since brackets denote an index  a 3   or a slice  a 3 5   of a list   a SyntaxError since  1 10  is invalid  and  a double off-by-one error since range 1 10  is  1  2  3  4  5  6  7  8  9   and you seem to want  0  1  2  3  4  5  6  7  8  9  10    And string    string    i is a TypeError since you can t add an integer to a string  unlike JavaScript    Look at the documentation for Python s new string formatting method  it is very powerful

You can use a generator to do this     def sequence generator limit             A generator to create strings of pattern - gt  string1 string2  stringN         inc    0     while inc  lt  limit          yield  string  str inc          inc    1    to generate a generator  notice i have used    instead of    a generator      s for s in sequence generator 10      to generate a list a list      s for s in sequence generator 10      to generate a string a string             join s for s in sequence generator 10

If we want output like  string0123456789  then we can use map function and join method of string     gt  gt  gt   string     join map str xrange 10     string0123456789    If we want List of string values then use list comprehension method     gt  gt  gt    string  i for i in map str xrange 10      string0    string1    string2    string3    string4    string5    string6    string7    string8    string9     Note   Use xrange   for Python 2 x  USe range   for Python 3 x
