- Returns a float range: e.g., for i in range(0.1, 1.0, 0.1): print(i)
prints the numbers .1, .2, .3, ... .9, 1.: 0.1 through 1.0 inclusive
Use it like range/irange (with 1, 2, or 3 arguments).
- Returns an inclusive range: e.g., for i in range(1,10): print(i)
prints the numbers 1 through 10 inclusive
Use it like range (with 1, 2, or 3 arguments), but with irange the stop
value is in the range
- leading(text, c=' ', extra=0)
- Returns a string of all c, whose length is the # of c's at the front of text
e.g., length('xxxyy','x') returns 'xxx'
- read_file_values(file, sep=None, conversions=None)
- Iterator for reading values sequentially from a file, regardless of
where they appear on lines.
If conversion is None, the string token is returned; if it is a list
of conversion functions, then they they are applied (circularly) to
each read string.
Example read_file_values(file,conversions=[str,int,int] will read/return
a string, an int, an int, a string, an int, an int, a string, ....
- safe_open(prompt_text, mode, error_message, default='')
- Prompts the user for a file (openable in mode) with and error message
to display if opening the file in that mode fails)
If mode=='w', and the file exists, the user will be prompted whether to overwrite it
If default is supplied, it will appear in the prompt and be the file
opened if the user just presses enter
- Returns the type of x as a nice string
For example: type(a) returns "<class 'xxxxxxxx'>; this function extracts the
'xxxxxxx' part: the first ' is at index 8; the last ' is at index -2
