Python_ How to stitch multiple small characters into large characters?

Case:

Here's a list of how to stitch this list up into a string?

L = [1, 2, 3, 4, ' A ', ' B ', ' C ']

What are the methods?

Method 1: for iterative stitching

#!/usr/bin/python3def Go_str (L):    median = ' for    i in L:        # To determine if the string type is if        isinstance (i, str):            median + = i        # if non-string, convert to string        else:            i = str (i)            median + = i    return medianif __name__ = = ' __main__ ':    # Initialization L    = List L = [1, 2, 3, 4, 4.5, ' a ', ' B ', ' C ']    new_str = go_str (l)    print (NEW_STR)

Method 2: Splicing by join

#!/usr/bin/python3def Go_str (L):    # list parsing, [str (i) for I in L], but not optimal, will generate a list again    # return '. Join ([STR (i) for i in L])        # generates an iterator (str (i) for I in L), and no additional parentheses return ' is required in the join    . Join (STR (i) for I in L) if __name__ = = ' __main__ ': 
   # Initialize l list    L = [1, 2, 3, 4, 4.5, ' a ', ' B ', ' C ']    new_str = go_str (l)    print (NEW_STR)
