Print Python Built-In Function Documentation
Question:
Write a program to print some Python built-in functions documents, such as abs(), int(), raw_input(). The built-in document method is __doc__.
Program:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
print abs.__doc__ print int.__doc__ print raw_input.__doc__ def square(num): '''Return the square value of the input number. The number must be integer. ''' return num ** 2 print square(2) print square.__doc__ |
Explanation:
Python documentation strings (or docstrings) provide a convenient way of associating documentation with Python modules, functions, classes, and methods. An object’s docsting is defined by including a string constant as the first statement in the object’s definition
Output:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 |
abs(number) -> number Return the absolute value of the argument. int(x=0) -> int or long int(x, base=10) -> int or long Convert a number or string to an integer, or return 0 if no arguments are given. If x is floating point, the conversion truncates towards zero. If x is outside the integer range, the function returns a long instead. If x is not a number or if base is given, then x must be a string or Unicode object representing an integer literal in the given base. The literal can be preceded by '+' or '-' and be surrounded by whitespace. The base defaults to 10. Valid bases are 0 and 2-36. Base 0 means to interpret the base from the string as an integer literal. >>> int('0b100', base=0) 4 raw_input([prompt]) -> string Read a string from standard input. The trailing newline is stripped. If the user hits EOF (Unix: Ctl-D, Windows: Ctl-Z+Return), raise EOFError. On Unix, GNU readline is used if enabled. The prompt string, if given, is printed without a trailing newline before reading. 4 Return the square value of the input number. The number must be integer. |
