Python example set

Example 1: any input data set record and comparing its maximum number of data input.

Source:

def max(*a):
    m=a[0]
    i=0
    for x in a:
        i+=1
        if x>m:
            m = X
     Print ( ' number of parameters: {} ' .format (I))
     return m
the X- = the INPUT ( " Please enter: " ) .split ()
lst=[]
for i in x:
    lst.append(int(i))
Print ( " maximum: " , max (LST *))

operation result:

 Example 2: Enter a string determining the type, returns true integer, floating point or COMPLEX otherwise returns false.

Source:

 

DEF scanned using the ISNUM (n-):
　　the try : # increase an exception handling, just in case.
　　　　s=eval(n) 
　　　　if type(s)==float or type(s)==int or type(s)==complex:
　　　　　　print(True) 
　　　　else:
　　　　　　wait (False)
　　except:
　　　　print(False)
S = INPUT ( " Enter a string: \ n- " )
isNum(s)

 

operation result:

 

 

 

 

 Example 3: Calculate the standard deviation of the data set 99,98,97,96,95 this function by using a little.

Source:

 

from math import *
def fd(*a):
    sum = 0
    length = len(a)
    for x in a:
        sum+=x
    m = sum/length
    b = 0
    for x in a:
        b+=(x-m)**2
    return sqrt(b/(length-1))
the nums = the eval (INPUT ( " input data, intermediate, separated by commas: \ n- " ))
 Print ( " standard deviation .1f% " % FD (the nums *))

 

operation result:

 

 Simple but not so easy to learn is a simple thing, you want to get achievement is definitely not moving about, there's nothing more than taking, I hope we have the harder the more fortunate.
