Python string methods

La méthode split() décompose une chaîne de caractères à l'endroit du séparateur spécifié et retourne une liste de chaînes de caractères.

La syntaxe de split() est :

str.split([separator, [maxsplit]])

paramètre split()

La méthode split() peut utiliser au maximum2un paramètre :

• separator(Optional)-Is a separator. The string is split at the specified separator (separator).　
  If the separator is not specified, any whitespace (spaces, newline characters, etc.) is a separator.

• maxsplit(Optional)- maxsplit defines the maximum number of splits.
  The default value is maxsplit-1, indicating that the split count is unlimited.

split() return value

split() splits the string at the separator and returns a list of strings.

Example1How does split() work in Python?

text = 'Love thy neighbor'
# Split at spaces
print(text.split())
grocery = 'Milk, Chicken, Bread'
# Split at ','
print(grocery.split(', '))
# Split at ':'
print(grocery.split(':'))

When running the program, the output is:

['Love', 'thy', 'neighbor']
['Milk', 'Chicken', 'Bread']
['Milk, Chicken, Bread']

Example2How does split() work when maxsplit is specified?

grocery = 'Milk, Chicken, Bread, Butter'
# maxsplit:　2
print(grocery.split(', '))　2))
# maxsplit:　1
print(grocery.split(', '))　1))
# maxsplit:　5
print(grocery.split(', '))　5))
# maxsplit: 0
print(grocery.split(', ', 0))

When running the program, the output is:

['Milk', 'Chicken, Bread, Butter']
['Milk', 'Chicken, Bread, Butter']
['Milk', 'Chicken', 'Bread', 'Butter']
['Milk, Chicken, Bread, Butter']

If maxsplit is specified, the list will contain at most maxsplit+1Project.
