●  A high order function accepts one or more functions as input and returns a new function. Sometimes it is required to use function as data. 

●  To make high order function, one need the import functools module. 

●  The functools.partial() function is used often for high order function.

A random item from a list, tuple, or string.

A random float r, such that 0 is less than or equal to r and r is less than 1.

It gets the length of the string that you pass to it then returns it as a number. Play with it.

Here, function name contains spaces. But function name should be a valid Python identifier with no spaces in between. And here, no variable is defined to obtain value being input. Lines 4 and 6 are badly indented; being part of same function, those should be at the same indentation level as that of lines 2, 3, 5 and 7. And also, variable favourite-game is an invalid identifier as it contains a hyphen, but it should have been an underscore.

#!/usr/bin/python 

name=raw_input(‘Enter your name :’) 

print (“Hi %s, Let us be friends!” % name);

a = 5

b = 9 

def swap(c,d): 

return d,c 

swap(a,b)

sqrt() and pow() are two libarary functions of math.h.

Two functions of stdlib.h are atoi() and itoa().

Two functions of string.h are strlen() and strcpy()

Two functions of ctype.h are isalpha() and isdigit().

The function tolower() converts an uppercase letter to a lower case letter.

The function toupper() converts lower case letters to upper case letters.

Tan(x) function return the tangent of x radians.

The output of ispunct (‘@’) is 1 means it is TRUE.

The output of toascii (‘A’) is 65.

It converts angle x from radians to degrees.

The output of isdigit (‘3’) is 1 means it is TRUE.

The output is 0! = 120

Because the address of variable ‘a’ is given to the variable ‘n’ of the function fact(call by reference method). So the function changes its value (i.e. n- -) to 0. Hence the result.

To get the desired result call the function as call by value method in this method the copy of the value of the variable ‘a’ is given to the function. So the actual value of ‘a’ will not changed. So instead of int fact(int &n) just write int fact(int n), i.e., no need of & symbol.

It returns True if the argument is a digit from 0 through 9 or an alphabetic character (either uppercase or lowercase) otherwise returns False.

cos() is a mathematical function that returns the cosine value for the given radians.

The output of sqrt(25) is 5.

exp() is a mathematical function that returns the natural logarithm base “e” raised to the argument’s power.

All the outputs will be 1, since the value of the objects attribute (X) is never changed.

X is now a part of the public members of the class C. Thus it can be accessed directly

The method floor() returns floor of x – the largest integer not greater than x. 

Syntax: Following is the syntax for floor() method 

import math 

math.floor(x) 

Note: This function is not accessible directly so we need to import math module and then we need to call this function using math static object. 

Parameters : x — This is a numeric expression. 

Return Value: This method returns largest integer not greater than x. 

Example: The following example shows the usage of floor() method. 

# !/usr/bin/python 

import math # This will import math module print “math.floor(-45.17): “, 

math.floor(-45.17) 

print “math.floor(100.12): “, 

math.floor(100.12) 

print “math.floor(100.72): “, 

math.floor(100.72) 

print “math.floor(119L):”, 

math.floor(119L) 

print “math.floor(math.pi):”, math.floor(math.pi) 

This will produce the following result: math.floor(-45.17) :-46.0

math.floor(100.12):100.0 

math.floor(100.72): 100.0 

math.floor(119L): 119.0 

math.floor(math.pi): 3.0

A variable that is not initialized (defined), perhaps a variable/function that is misspelled.

The cell() function gives the smallest integer not less than the given value.

It returns the ceiling of x as a float, the smallest integer value greater than or equal to x.

It returns the floor of x as a float, the largest integer value less than or equal to x.

Returns the cosine of x radians.

Returns the base-10 logarithm of x. This is usually more accurate than log(x,10).

Returns the square root of x.

print type([l,2])

< type’list’>

< type’complex’>

log₃ [log₂ (log₃ x)] = 1 

∴ log₂ (log₃ x) = 3¹ 

∴ log₃ x = 2³ 

∴ log₃ x = 8 

∴ x = 3⁸ 

∴ x = 6561
