Python Programming \u2013 Random module<\/h2>\n

Random module<\/strong><\/p>\n

This module implements pseudo-random number generators for various distributions. Almost all module functions depend on the basic function random ( ), which generates a random float uniformly in the semi-open range [0 . 0 , 1 . 0 ). Python uses the “Mersenne Twister” as the core generator. However, Mersenne Twister being completely deterministic, it is not suitable for all purposes and is completely unsuitable for cryptographic purposes.<\/p>\n

Functions for integers<\/strong><\/p>\n

random.randrange ( stop )<\/p>\n

Return a randomly selected integer element from range ( 0 , stop ) .<\/p>\n

>>> random . randrange ( 88 )\r\n17\r\n>>> random . randrange ( -88 )\r\n\r\nTraceback ( most recent call last ) :\r\nFile \"<pyshell#l>\" , line 1 , in <module> \r\nrandom . randrange ( -88 )\r\nFile \" C : \\ Python27 \\ lib \\ random . py \" , line 191 , in randrange \r\nraise ValueError , \" empty range for randrange ( ) \"\r\nValueError: empty range for randrange ( )<\/pre>\n
random . randrange ( start , stop [ , step ] )
\nReturn a randomly selected integer element from range ( start , stop , step ) .<\/p>\n
>>> random . randrange ( 3 , 100 , 5 )\r\n83<\/pre>\n
random . randint ( a , b )
\nReturn a random integer N such that a<=N<=b.<\/p>\n
>>> random . randint ( 5 , 86 )\r\n70<\/pre>\n
Functions for sequences<\/strong><\/p>\n
random . choice ( seq )
\nReturn a random element from the non-empty sequence seq. If seq is empty, raises IndexError.<\/p>\n
>>> random . choice ( ' abcdefghij ' )\r\n' e ' \r\n>>> random . choice ( [ ' aa ' , ' bb ' , ' cc ' , 11 , 22 ] )\r\n' cc '<\/pre>\n
random . shuffle ( x [ , random ] )
\nShuffle the sequence x in place. The optional argument random is a O-argument function returning a random float in [ 0 . 0 , 1 . 0 ); by default, this is the function random ( ).<\/p>\n
>>> items= [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]\r\n>>> random . shuffle ( items )\r\n>>> items\r\n[ 4 , 7 , 2 , 6 , 3 , 5 , 1 ]<\/pre>\n
random . sample ( population , k )
\nReturn a k length list of unique elements chosen from the population sequence; used for random sampling without replacement. Return a new list containing elements from the population, while leaving the original population unchanged. If the population contain repeating elements, then each occurrence is a possible selection in the sample.<\/p>\n
>>> random . sample ( [ 1 , 2 , 3 , 4 , 5 ] , 3 )\r\n[ 4 , 5 , 1 ]<\/pre>\n
To choose a sample from a range of integers, use an xrange ( ) object as an argument. This is especially fast and space efficient for sampling from a large population.<\/p>\n
>>> random . sample ( xrange ( 10000000 ) , 5 )\r\n[ 2445367 , 2052603 , 975267 , 3021085 , 6098369 ]<\/pre>\n
Functions for floating point values<\/strong><\/p>\n
random . random ( )
\nReturn the next random floating point number in the range [ 0 . 0 , 1 . 0 ).<\/p>\n
>>> random . random ( )\r\n0.6229016948897019<\/pre>\n
random . uniform ( a , b )
\nReturn a random floating point number N, such that a<=N<=b for a<=b and b<=N<=a for b<a.<\/p>\n
>>> random . uniform ( 0 . 5 , 0 . 6 )\r\n0.5795193565565696<\/pre>\n
random . triangular ( low , high , mode )
\nReturn a random floating point number N such that low<=N<=high and with the specified mode between those bounds. The low and high bounds default to 0 and 1, respectively. The mode argument defaults to the midpoint between the bounds, giving a symmetric distribution.<\/p>\n
>>> random . triangular ( 2 . 8 , 10 . 9 , 7 . 5 )\r\n6.676127015045406<\/pre>\n
random . betavariate ( alpha , beta )
\nBeta distribution; conditions of the parameters are alpha>0 and beta>0. Returned values range between 0 and 1.<\/p>\n
>>> random . betavariate ( 2 . 5 , 1 . 0 )\r\n0.543590525336106<\/pre>\n
random . expovariate ( lambd )
\nExponential distribution; lambd is 1.0 divided by the desired mean. It should be nonzero. Returned values range from 0 to positive infinity; if lambd is positive, and from negative infinity to 0, if lambd is negative.<\/p>\n
>>> random . expovariate ( 0 . 5 )\r\n1.5287594548764503<\/pre>\n
random . gammavariate ( alpha , beta )
\nGamma distribution (not the gamma function). Conditions of the parameters are alpha>0 and beta>0.<\/p>\n
>>> random . gammavariate ( 1 . 3 , 0 . 5 )\r\n0.5893587279305473<\/pre>\n
random . gauss ( mu , sigma )
\nGaussian distribution; mu is the mean, and sigma is the standard deviation. This is slightly faster than the normalvariate () function defined below.<\/p>\n
>>> random . gauss ( 0 . 5 , 1 . 9 )\r\n-1.8886943114939512<\/pre>\n
random . lognormvariate ( mu , sigma )
\nLog normal distribution; if natural logarithm of this distribution is taken, a normal distribution with mean mu, and standard deviation sigma is received, mu can have any value, and sigma must be greater than zero.<\/p>\n
>>> random . lognormvariate ( 0 . 5 , 1 . 9 )\r\n4.621063728160664<\/pre>\n
random . normalvariate ( mu , sigma )
\nNormal distribution; mu is the mean, and sigma is the standard deviation.<\/p>\n
>>> random . normalvariate ( 0 . 5 , 1 . 9 )\r\n1.6246107732503214<\/pre>\n
random . vonmisesvariate ( mu , kappa )
\nmu is the mean angle, expressed in radians between 0 and 271, and kappa is the concentration parameter, which must be greater than or equal to zero. If kappa is equal to zero, this distribution reduces to a uniform random angle over the range 0 to 2K .<\/p>\n
>>> random . vonmisesvariate ( 0 . 5 , 1 . 9 )\r\n-0.4664831190641767<\/pre>\n
random . paretovariate ( alpha )
\nPareto distribution; alpha is the shape parameter.<\/p>\n
>>> random . paretovariate ( 0 . 5 )\r\n60.471412103322585<\/pre>\n
random . weibullvariate ( alpha , beta )
\nWeibull distribution; alpha is the scale parameter and beta is the shape parameter.<\/p>\n
>>> random . weibullvariate ( 0 . 5 , 1 . 9 )\r\n0.9229896561284915<\/pre>\n
Alternative generators<\/strong><\/p>\n
Apart from Mersenne Twister, there are more core random number generator, such as generator based on “Wichmann-Hill” algorithm.<\/p>\n
>>> rnd=random . WichmannHill ( )\r\n>>> rnd . random ( )\r\n0.4065226158909223\r\n>>>\r\n>>> rnd=random . SystemRandom ( )\r\n>>> rnd . random ( )\r\n0.46579102190832355<\/pre>\n","protected":false},"excerpt":{"rendered":"
