TypeError: 在字符串格式化过程中并非所有参数都被转换是什么意思？

Question

这是我的第一个程序，它基本上以不同的声音大声说出内容：

import os
print "Hello, Welcome to the speaking program"
speak = raw_input("What would you like to say?\n")
type = raw_input("Would you like\n1. Normal Voice\n2. High Pitched\n3. Low Pitched?\n4. Whisper\n5. Indian Voice\n Please choose 1,2,3,4 or 5\n")

if type == "1":
    os.system("say %s " % speak)
if type == "2":
   os.system("say -v good %s" % speak)
if type == "3":
    os.system("say -v bad %s" % speak)
if type == "4":
    os.system("say -v whisper %s" % speak)
if type == "5":
    os.system("say -v sangeeta $s" % speak)
if type < "5":
    os.system("echo that is not an option")

finish = raw_input("I have done the job, Pick an option\n1. Quit\n2. New Word\n3. Change Pitch\n")

if finish == "1":
    quit()
if finish == "2": 
    os.system("clear")
    os.system("python speak.py")
if finish == "3": 
    type2 = raw_input("Would you like\n1. Normal Voice\n2. High Pitched\n3. Low Pitched\nor\n4. Whisper voice?\n5.Indian Voice\n")    
    if type2 == "1":
        os.system("say %s " % speak)
    if type2 == "2":
        os.system("say -v good %s" % speak)
    if type2 == "3":
        os.system("say -v bad %s" % speak)
    if type == "4":
        os.system("say -v whisper %s" % speak)
    if type == "5":
        os.system("say -v Sangeeta %s" % speak)

    else:
        print "That is not an option"
        os.system("clear")
        os.system("python speak.py")

else:
    print "That is not an option !!! "
    os.system("clear")
    os.system("python speak.py")

finish = raw_input("I have done the job, Pick an option\n1. Quit\n2. New Word\n3. Change Pitch\n")
if finish == "1":
    os.system("logout")
    os.system("killall Terminal")
if finish == "2": 
    os.system("clear")
    os.system("python speak.py")
if finish == "3": 
    type3 = raw_input("Would you like \n1. Normal Voice\n2. High Pitched\n3. Low Pitched?\n4. Whisper voice\n5.Indian Voice\n")    
    if type3 == "1":
        os.system("say %s " % speak)
    if type3 == "2":
        os.system("say -v good %s" % speak)
    if type3 == "3":
        os.system("say -v bad %s" % speak)
    if type3 == "4":
        os.system("say -v whisper %s" % speak)
    if type3 == "5":
        os.system("say -v Sangeeta %s" % speak)
    else:
        print "That is not an option"
        os.system("clear")
        os.system("python speak.py")

这就是错误：

Shameers-MacBook-Pro:Test Programs Shameer$ !!
python speak.py 
Hello, Welcome to the speaking program
What would you like to say?
hello
Would you like
1. Normal Voice
2. High Pitched
3. Low Pitched?
4. Whisper
5. Indian Voice
 Please choose 1,2,3,4 or 5
5
Traceback (most recent call last):

    os.system("say -v sangeeta $s" % speak)
TypeError: not all arguments converted during string formatting

请帮助我。我还年轻，需要一些帮助。如果您不想回答，只会投反对票。

Answer 1

您输入美元符号而不是百分号：

os.system("say -v sangeeta $s" % speak)

这应该是：

os.system("say -v sangeeta %s" % speak)
