27 !!DESCRIPTION
28
29
30 Python is an interpreted, interactive, object-oriented
31 programming language that combines remarkable power with
32 very clear syntax. For an introduction to programming in
33 Python you are referred to the Python Tutorial. The Python
34 Library Reference documents built-in and standard types,
35 constants, functions and modules. Finally, the Python
36 Reference Manual describes the syntax and semantics of the
37 core language in (perhaps too) much detail.
38
39
40 Python's basic power can be extended with your own modules
41 written in C or C++. On most systems such modules may be
42 dynamically loaded. Python is also adaptable as an extension
43 language for existing applications. See the internal
44 documentation for hints.
45 !!COMMAND LINE OPTIONS
46
47
48 __-d__
49
50
51 Turn on parser debugging output (for wizards only, depending
52 on compilation options).
53
54
55 __-i__
56
57
58 When a script is passed as first argument or the __-c__
59 option is used, enter interactive mode after executing the
60 script or the command. It does not read the $PYTHONSTARTUP
61 file. This can be useful to inspect global variables or a
62 stack trace when a script raises an exception.
63
64
65 __-O__
66
67
68 Turn on basic optimizations. This changes the filename
69 extension for compiled (bytecode) files from ''.pyc'' to
70 ''pyo.''
71
72
73 __-S__
74
75
76 Disable the import of the module ''site'' and the
77 site-dependent manipulations of ''sys.path'' that it
78 entails.
79
80
81 __-t__
82
83
84 Issue a warning when a source file mixes tabs and spaces for
85 indentation in a way that makes it depend on the worth of a
86 tab expressed in spaces. Issue an error when the option is
87 given twice.
88
89
90 __-u__
91
92
93 Force stdin, stdout and stderr to be totally
94 unbuffered.
95
96
97 __-v__
98
99
100 Print a message each time a module is initialized, showing
101 the place (filename or built-in module) from which it is
102 loaded.
103
104
105 __-x__
106
107
108 Skip the first line of the source. This is intended for a
109 DOS specific hack only. Warning: the line numbers in error
110 messages will be off by one!
111
112
113 __-X__
114
115
116 Make the standard exceptions strings instead of classes. Use
117 for backward compatibility with old code only.
118
119
120 __-c__ ''command''
121
122
123 Specify the command to execute (see next section). This
124 terminates the option list (following options are passed as
125 arguments to the command).
126 !!INTERPRETER INTERFACE
127
128
129 The interpreter interface resembles that of the UNIX shell:
130 when called with standard input connected to a tty device,
131 it prompts for commands and executes them until an EOF is
132 read; when called with a file name argument or with a file
133 as standard input, it reads and executes a ''script''
134 from that file; when called with __-c__ ''command,''
135 it executes the Python statement(s) given as ''command.''
136 Here ''command'' may contain multiple statements
137 separated by newlines. Leading whitespace is significant in
138 Python statements! In non-interactive mode, the entire input
139 is parsed befored it is executed.
140
141
142 If available, the script name and additional arguments
143 thereafter are passed to the script in the Python variable
144 ''sys.argv ,'' which is a list of strings (you must first
145 ''import sys'' to be able to access it). If no script
146 name is given, ''sys.argv'' is empty; if __-c__ is
147 used, ''sys.argv[[0]'' contains the string '''-c'.''
148 Note that options interpreted by the Python interpreter
149 itself are not placed in ''sys.argv.''
150
151
152 In interactive mode, the primary prompt is `
153 sys.ps1'' or ''sys.ps2.'' The interpreter quits
154 when it reads an EOF at a prompt. When an unhandled
155 exception occurs, a stack trace is printed and control
156 returns to the primary prompt; in non-interactive mode, the
157 interpreter exits after printing the stack trace. The
158 interrupt signal raises the ''!KeyboardInterrupt''
159 exception; other UNIX signals are not caught (except that
160 SIGPIPE is sometimes ignored, in favor of the ''IOError''
161 exception). Error messages are written to
162 stderr.
163 !!FILES AND DIRECTORIES
164
165
166 These are subject to difference depending on local
167 installation conventions:
168
169
170 /usr/local/bin/python
171
172
173 Recommended location of the interpreter.
174
175
176 /usr/local/lib/python
177
178
179 Recommended location of the directory containing the
180 standard modules.
181 !!ENVIRONMENT VARIABLES
182
183
184 PYTHONHOME
185
186
187 Change the location of the standard Python libraries. By
188 default, the libraries are searched in
189
190
191 PYTHONPATH
192
193
194 Augments the default search path for module files. The
195 format is the same as the shell's $PATH: one or more
196 directory pathnames separated by colons. Non-existant
197 directories are silently ignored. The default search path is
198 installation dependent, but generally begins with
199 sys.path
200 .''
201
202
203 PYTHONSTARTUP
204
205
206 If this is the name of a readable file, the Python commands
207 in that file are executed before the first prompt is
208 displayed in interactive mode. The file is executed in the
209 same name space where interactive commands are executed so
210 that objects defined or imported in it can be used without
211 qualification in the interactive session. You can also
212 change the prompts ''sys.ps1'' and ''sys.ps2'' in this
213 file.
214
215
216 PYTHONDEBUG
217
218
219 If this is set to a non-empty string it is equivalent to
220 specifying the __-d__ option.
221
222
223 PYTHONINSPECT
224
225
226 If this is set to a non-empty string it is equivalent to
227 specifying the __-i__ option.
228
229
230 PYTHONUNBUFFERED
231
232
233 If this is set to a non-empty string it is equivalent to
234 specifying the __-u__ option.
235
236
237 PYTHONVERBOSE
238
239
240 If this is set to a non-empty string it is equivalent to
241 specifying the __-v__ option.
