PEP8 outlines that one line should not exceed 80 characters. Therefore, in order to write a single string that is longer than this we must either:

  • Use a backslash (\)

  • Uses parentheses

  • Use concatenation

Using backslash

A backslash is a continuation character:

s = 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa' \
'bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb'
print(s)
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb

Using parentheses

A parentheses can be used to break lines:

s = ('aaaaaaaaaaaaaaaaa'
'bbbbbbbbbbbbbbbbb'
'ccccccccccccccccc')
print(s)
aaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbccccccccccccccccc

Using concatenation

Note if you have variables that represent strings you will need to use concatenation:

x = 'bbbbbbbbbbbbbbbbbb'
y = 'aaaaaaaaaaaaaaaaaa' \
+ x + 'cccccccccccccc'
print(y)
aaaaaaaaaaaaaaaaaabbbbbbbbbbbbbbbbbbcccccccccccccc
