我在函数中添加了一个参数，以及多个参数。我还将变量移到函数之外，每次都会出错。需要def g_chord():
string_1 = "G note"
string_2 = "B note"
string_3 = "D note"
print "A 'G' chord consists of the 1st, 3rd, and 5th notes in the G scale. Those notes are a, %d, %d, and %d." % (string_1, string_2, string_3)
g_chord()
吗？
{{1}}

%d用于数字。请改用%s。

如果您尝试使用％d打印字符串，则会显示错误信息。
Traceback (most recent call last):
File "<stdin>", line 5, in <module>
TypeError: %d format: a number is required, not str
所以尝试用％s替换那些％d。
print "A 'G' chord consists of the 1st, 3rd, and 5th notes in the G scale. Those notes are a, %d, %d, and %d." % (string_1, string_2, string_3
