Question

我对python的经验很少，我相信即使我的标题也是不正确的措辞。我有一个程序，当你键入一个键列表并按Enter键时，它会播放一个音符。但是要使它工作，你需要在每个键之间按空格键。我想让它接受说eflkjh而不是e f l k j h。我该怎么做？

soundBinary = input(" > ")
for note in soundBinary.split():

    if note == "q":          #rest
        freq = 37
    elif note == "w":        #b
        freq = 280
    elif note == "e":        #b
        freq = 300
    elif note == "r":        #b
        freq = 320
    elif note == "t":        #b
        freq = 340
    elif note == "y":        #b
        freq = 360
    elif note == "u":        #b
        freq = 380
    elif note == "i":        #b
        freq = 400
    elif note == "o":        #b
        freq = 440
    elif note == "p":        #b
        freq = 460
    elif note == "a":        #b
        freq = 480
    elif note == "s":        #b
        freq = 500
    elif note == "d":        #b
        freq = 520
    elif note == "f":        #b
        freq = 540
    elif note == "g":        #b
        freq = 560
    elif note == "h":        #b
        freq = 580
    elif note == "j":        #high c
        freq = 600
    elif note == "k":        #low c
        freq = 620
    elif note == "l":        #d
        freq = 640
    elif note == "z":        #e
        freq = 660
    elif note == "x":        #f
        freq = 680
    elif note == "c":        #g
        freq = 700
    elif note == "v":        #a
        freq = 720
    elif note == "b":        #b
        freq = 740
    elif note == "n":        #b
        freq = 760
    elif note == "m":        #b
        freq = 780    

    winsound.Beep(freq, rate)

Answer 1

尝试以下方法：

for note in soundBinary:
    if note == "q":
        ....

示例：

string = "abcdefg"
for char in string:
    print char

输出：

scottsmudger@ns207588:~ $ python test.py
a
b
c
d
e
f
g

Answer 2

两部分：

（1）只需遍历输入字符串的字符：

for note in soundBinary:

这样可以按顺序为您提供字符，而无需拆分任何内容。

（2）构建一个参考字典并将其用作查找列表：

note_id : {
    'q':37, 'w':280, 'e':300, 'r':320, 't':340, 'y': 360,
    'u':380 # et cetera
}

现在，您的程序在上面的循环中使用它：

for note in soundBinary:
    winsound.Beep( note_id[note] )

这会让你感动吗？将该引用列表放在程序的顶部使得实际的逻辑流程更容易阅读。

在输入之前自动在输入中添加空格
