Determine the prime number in Python and in python
A = raw_input () # input number a = int (a) # forced conversion to intb = True # a mark for I in range (2, ): # Loop itself from 2 if a % I = 0: # if it can be divisible by B = False in addition to itself and 1 # mark it as False break # End of loop if B: print 'yes' else: print 'no'
Python code for prime numbers
I wonder if you can understand this?
This is equivalent code:
L1 = []
For x in range (1,100 ):
List = []
For y in range (2, x/2 + 1 ):
If x % y = 0:
List. append (y)
If not list:
L1.append (x)
Print L1
If the empty list is not [], True is returned.
In the original code, if not is followed by a temporary list. if this list is empty, it indicates that x has no factor> = 2. x must be a prime number, then add x to the master list.
[X for x in range (1,100) if express]
This statement only adds x when express is True.
Compile the code "How many prime numbers are there between-" in python?
A = 0
List = []
For I in range (101,200, 2 ):
Flag = 0
For j in range (2, I/2 + 1 ):
If (I % j = 0 ):
Flag = 0
Break
Else:
Flag = 1
Continue
If flag = 1:
List. append (I)
A + = 1
Print list
Print
