我需要有关Python入门的作业的帮助。
任务是让计算机选择1到100之间的随机数,并且用户必须猜测该数字。如果您的猜测太高,则会告诉您。如果您的猜测太低,则会告诉您。它将继续重复,直到您猜出所生成的正确数字为止。
我的问题是,如果输入是字符串,那么您会得到提示,说这不是可能的答案。如何解决此问题?
P.S。如果不太麻烦,我想获得有关如何修复代码而不是答案的提示。
代码:
import random
#answer= a
a= random.randint(1,100)
#x= original variable of a
x= a
correct= False
print("I'm thinking of anumber between 1 and 100, try to guess it.")
#guess= g
while not correct:
g= input("Please enter a number between 1 and 100: ", )
if g == "x":
print("Sorry, but \"" + g + "\" is not a number between 1 and 100.")
elif int(g) < x:
print("your guess was too low, try again.")
elif int(g) > x:
print("your guess was too high, try again.")
else:
print("Congratulations, you guessed the number!")
答案 0 :(得分:0)
因此,如果您要清理输入内容以确保仅输入数字,则可以使用[ [ [odd_clr_val,odd_clr_val,odd_clr_vlue] ... ] .... ]
方法进行检查。例如:
from PIL import Image
import numpy as np
import time
#if the value of pixel is:
#Odd = 0 , even = 1
#We make every element odd
img = Image.open('Desktop/test.jpg')
arr = np.array(img)
x,y,z = np.shape(arr)
count = 0
initial = time.time()
#This nested loop makes every element odd but is very slow and in need to be optimized
for i in range(x):
for j in range(y):
count += 1
k = arr[i][j]
arr[i][j][0] = k[0] + int(not(k[0]%2)) # adds 1 if k[i] is odd else 0
arr[i][j][1] = k[1] + int(not(k[1]%2))
arr[i][j][2] = k[2] + int(not(k[2]%2))
print("Time delta: %f"%(time.time() - initial ))
print("The amount of data you can store in this image is: %d kiBs"%((count*3)/1024))
#every element of this image is odd now
z = input("Enter the string:")
long_array = []
for i in z:
long_array += list(map(int,list(format(ord(i), '#010b')[2:])))
#everything is in binary now
counter = 0
try:
for i in range(x):
for j in range(y):
k = arr[i][j]
arr[i][j][0] = k[0] if not(long_array[counter]) else k[0]+1
counter += 1
arr[i][j][1] = k[1] if not(long_array[counter]) else k[1]+1
counter += 1
arr[i][j][2] = k[2] if not(long_array[counter]) else k[2]+1
counter += 1
except IndexError:
print("Done")
except:
print("An unidentified error occured!")
image = Image.fromarray(arr)
image.show()
image.save("secret.png")
