Concatting strings

concatting-strings.py

# The "idiomaitc" way to concat strings in Python is

characters = ('a', 'b', 'c')
string = ''.join(characters)

# What's nice is that we can store all the strings in a list

characters = list()

for codepoint in range(ord('a'), ord('z') + 1):
    character = chr(codepoint)
    characters.append(character)

# And concatenate that

string = ''.join(characters)

# Which, especially for larger strings, ends up being more efficient--

characters = ''

for codepoint in range(ord('a'), ord('z') + 1):
    character = chr(codepoint)
    characters += character

# This way, we create a *new* string *every iteration* of the loop. If it's 1,000,000 characters long, you can imagine--that's quite an overhead!
