AmigaOS Manual: Python Methods

Built-in Methods for Strings

.capitalize()

<stringobject>.capitalize()

Returns a string where the first character is uppercase. For example:

text = "python for everybody."
txt = text.capitalize()
print( txt )

Output:

  Python for everybody.

.center()

<stringobject>.center(<length>[, <fillchar>])

Returns a string that is aligned to the center using character <fillchar>. The returned string is <length> characters long. If the specified length is less than the <stringobject> string's length, the original <stringobject> will be returned. If you omit the fill character, space will be used as a filler.

For example:

text = "The Core of the Sun"
txt = text.center( 25, '-' )
print( txt )

Output:

  ---The Core of the Sun---

.count()

<stringobject>.count(<substring>[, <start>][, <end>])

Returns the number of times the supplied string <substring> appears in the <stringobject> string. By default .count() searches the <substring> from the beginning of the <stringobject> string to the end of the string.

You can change the search range with the start and end parameters. The start parameter specifies the string position where the search range should start (0 is the start of the string) and the end parameter the string position where the search should end.

For example:

text = "I love AmigaOS. AmigaOS is my favourite operating system."
times = text.count( "AmigaOS" )
print( times )

Output:

  2

.decode()

<stringobject>.decode([encoding=<encoding>][, errors=<errors>])

Decodes an encoded <stringobject> string and returns the result to the caller. The optional encoding parameter specifies the codec to use and the optional errors parameter the error handling method. If the encoding parameter is omitted, codec UTF-8 will be used.

The full list of available codecs is as follows:

• .encode()

.encode()

<stringobject>.encode([encoding=<encoding>][, errors=<errors>])

This method encodes the string <stringobject> and returns the result to the caller. The optional encoding parameter specifies the encoding codec to be used. See .decode() for available codecs. If the codec is omitted, UTF-8 will be used.

The optional errors parameter allows you to change the handling scheme. See .decode() for the legal values.
