05-python learning the fifth day - simple code

It can be made simply by python random number codes.

1.0 versions, and this code, only one code, although not up to function, logic, or accurate, we can not be considered a verification code, but we will continue to improve.

Import Random   # introducing a random number function Random 
checkcode = ''       # set a variable empty, as codes

for I in Range (. 4):   # cycle numbers between 0. 4 
    checkcode = + STR (I)   # each string into digital
    
Print (checkcode)     # output out

 

The result: 0123 (each time the fixed numbers) Oh

Version 1.1 came, we use a random number, plus a random code can be generated.

Import Random   # introducing a random number function Random 
checkcode = ''       # set a variable empty, as codes

for i in range(4):
    Current = the random.randint (0,9)    # of each cycle a random number it 
    checkcode = + STR (Current)

Print (checkcode)     # output out

 

The result: a four-digit code 6151 was born.

? Version 1.2 came, the students said pure digital so do not fly, the level is too low, insecurity, you can not add the letter I said: Well that is not simple, add the letter is not on the list thing.

# The Author: Dwdar 
Import Random   # introducing a random number function Random 

checkcode = ''   # set a variable empty, as codes

for i in the Range (4 ):
     # adding the letter 
    Current random.randrange = (0, 4)   # guess, I generated random number and i will not be equal to it? 
    IF Current I ==:   # If guessed 
        temp = CHR (the random.randint (65, 90))   # then identify any input ASCII codes, converting it to put letters temp saved. 
    # Add digital 
    the else :
        temp = the random.randint (0,. 9)   # If there is no knife, it is the original number between 0 to 9, temp kept up into 
    checkcode = + STR (temp)   # to keep up with them can generate temp a combination of numbers or letters of the set of data.

print(checkcode)

 

The results are: 24G4, may generate a combination of letters and numbers (sometimes pure digital and pure letters), and relatively good instrument allows to verify the code. If you want to make a six-figure, as long as the two 4-6 can be changed.

1.3 versions, the 6-digit alphanumeric combination codes.

# The Author: Dwdar 
Import Random   # introducing a random number function Random 

checkcode = ''   # set a variable empty, as codes

for i in the Range (6 ):
     # adding the letter 
    Current random.randrange = (0, 6)   # guess, I generated random number and i will not be equal to it? 
    IF Current I ==:   # If guessed 
        temp = CHR (the random.randint (65, 90))   # then identify any input ASCII codes, converting it to put letters temp saved. 
    # Add digital 
    the else :
        temp = the random.randint (0,. 9)   # If there is no knife, it is the original number between 0 to 9, temp kept up into 
    checkcode = + STR (temp)   # to keep up with them can generate temp a combination of numbers or letters of the set of data.

print(checkcode)

The result: 889 152
