打印在函數內存儲字符串的變量-Python

Question

我向該函數添加了一個參數，以及多個參數。 我也將變量移到函數之外，每次都會出現錯誤。 需要str()嗎？

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()

Answer 1

%d用於數字。 請改用%s 。

Answer 2

如果嘗試使用％d打印字符串，它將給您錯誤。

Traceback (most recent call last):
File "<stdin>", line 5, in <module>
TypeError: %d format: a number is required, not str

因此請嘗試將這些％d替換為％s。 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
