Python have many, useful functions to work with string. This post I will demonstrate some functions I frequently use.
Let's start!
split : Splitting a string using space as delimiter by default and return a list
>>> paragraph = "Python is an interpreted, high-level, general-purpose programming language. Created by Guido van Rossum and first released in 1991."
>>> word_list = paragraph.split()
>>> word_list
['Python',
'is',
'an',
'interpreted,',
'high-level,',
'general-purpose',
'programming',
'language.',
'Created',
'by',
'Guido',
'van',
'Rossum',
'and',
'first',
'released',
'in',
'1991.']
# You can change delimiter too
>>> word_list_split_by_comma = paragraph.split(',')
>>> word_list_split_by_comma
['Python is an interpreted',
' high-level',
' general-purpose programming language. Created by Guido van Rossum and first released in 1991.']
join : Combine list of string to single string with custom delimeter
>>> word_list
['Python',
'is',
'an',
'interpreted,',
'high-level,',
'general-purpose',
'programming',
'language.',
'Created',
'by',
'Guido',
'van',
'Rossum',
'and',
'first',
'released',
'in',
'1991.']
>>> "|".join(word_list)
'Python|is|an|interpreted,|high-level,|general-purpose|programming|language.|Created|by|Guido|van|Rossum|and|first|released|in|1991.'
# OR
>>> "|".join(paragraph.split())
'Python|is|an|interpreted,|high-level,|general-purpose|programming|language.|Created|by|Guido|van|Rossum|and|first|released|in|1991.'
Slicing : You can slice string as same as list.
>>> first_25_chars = paragraph[:25]
first_25_chars
'Python is an interpreted,'
>>> last_25_chars = paragraph[-25:]
>>> last_25_chars
'd first released in 1991.'
>>> reverse_paragraph = paragraph[::-1]
>>> reverse_paragraph
'.1991 ni desaeler tsrif dna mussoR nav odiuG yb detaerC .egaugnal gnimmargorp esoprup-lareneg ,level-hgih ,deterpretni na si nohtyP'
len & count: string length & counting occurrence sub string
>>> len(paragraph) # This can tell how many index we can use when slicing
131
>>> paragraph.count("ed")
6
For fun
Use center to centering your text, with amount of supply width spaces and custom character replacement rather than space.
>>> "TADA!".center(30, "π")
'ππππππππππππTADA!πππππππππππππ'
