尝试在 Python 3 中调用数组（列表）中的范围

Question

enter code here


from array import *

# Set up Array
firstArray = array('i', [0,0,0,0,0,0])
secondArray = array("i",[0,0,0,0,0,0])

# Program Greeting
print("This program prompts the client for 6 numbers.")
print("If a number is over 100, move it to a second array.")
print()

# Load numbers from client
for i in range(0,5,1):
    numIn = int(input("Enter a number: ")) == firstArray[i]
    firstArray[i] = numIn

# Move numbers over 100 to 2nd array
print("Searching through the array and moving numbers.")
secArrayCntr = 1
for i in range(0,5,1):
    if firstArray[i] <= 1:
        secondArray[secArrayCntr] = firstArray[i]
        secArrayCntr = secArrayCntr + 1

# Print First Array
print("Displaying the first array.")
for i in range(0,5,1):
    print(firstArray[i])

# Print Second Array
print("Displaying ", secArrayCntr, " numbers over 100.")
for i in range(1, secArrayCntr, 1):
    print(secondArray[i])

''' 不明白为什么它显示0。如果你们有帮助，请尝试让代码看起来对新手程序员来说很熟悉。任何提示都会很棒。 谢谢。

它显示零是因为您将一个可能为 False 的布尔值作为值。

numIn = int(input("Enter a number: ")) == firstArray[i]

如果您想让用户输入数字，只需将其放入变量中，然后放入数组中（如果不会发生其他操作，您可以直接进行）。检查您的代码的以下转换：

from array import *

# Set up Array
firstArray = array('i', [0,0,0,0,0,0])
secondArray = array("i",[0,0,0,0,0,0])

# Program Greeting
print("This program prompts the client for 6 numbers.")
print("If a number is over 100, move it to a second array.")
print()

# Load numbers from client
for i in range(0,5,1):
    number = int(input("Enter a number: ")) 
    firstArray[i] = number

# Move numbers over 100 to 2nd array
print("Searching through the array and moving numbers.")
secArrayCntr = 1
for i in range(0,5,1):
    if firstArray[i] > 100: # If it's over 100 than it can't be <1
        secondArray[secArrayCntr] = firstArray[i]
        secArrayCntr = secArrayCntr + 1

# Print First Array
print("Displaying the first array.")
for i in range(0,5,1):
    print(firstArray[i])

# Print Second Array
print("Displaying ", secArrayCntr, " numbers over 100.")
for i in range(1, secArrayCntr, 1):
    print(secondArray[i])

，结果为：

This program prompts the client for 6 numbers.
If a number is over 100, move it to a second array.

Enter a number: 3
Enter a number: 300
Enter a number: 700
Enter a number: 4
Enter a number: 7
Searching through the array and moving numbers.
Displaying the first array.
3
300
700
4
7
Displaying  3  numbers over 100.
300
700

要获得超过 100 的数字（就像在您的一个 cmets 中一样，我不得不更改这一行）：

if firstArray[i] <= 1:

，到这里：

if firstArray[i] > 100:
