Python:声明为整数和字符

Question

# declare score as integer
score = int

# declare rating as character
rating = chr

# write "Enter score: "
# input score
score = input("Enter score: ")

# if score == 10 Then
#   set rating = "A"
# endif
if score == 10:
    rating = "A"

print(rating)

当我执行此代码并输入“10”时，我在 shell 中得到了内置函数 chr。我希望它根据分数打印 A 或其他字符。例如，如果输入分数是 8 或 9，则必须读取 B。但是，我试图首先通过第一步。我是编程新手，如果我能指出正确的方向，那将大有帮助。

在 python 中，你不能做静态类型(即你不能将变量固定为类型)。 Python 是动态类型。

您需要的是强制输入变量的类型。

# declare score as integer
score = '0' # the default score

# declare rating as character
rating = 'D' # default rating

# write "Enter score: "
# input score
score = input("Enter score: ")

# here, we are going to force convert score to integer
try:
    score = int (score)
except:
    print ('score is not convertable to integer')

# if score == 10 Then
#   set rating = "A"
# endif
if score == 10:
    rating = "A"

print(rating)
