並非在字符串格式化過程中轉換的所有參數

Question

我正在學習Python。在做練習時，我得到錯誤

Python TypeError: not all arguments converted during string formatting

我已經搜索了答案，但我不明白我找到的代碼。

print "What's your name?", 
name = raw_input() 
print "What's your middle name?", 
middle_name = raw_input() 
print "Where do you live?", 
country = raw_input() 
print "Make of the car you drive?", 
car = raw_input() 
print "Are you single or married?", 
socstatus = raw_input() 
print "Are you Men or Woman?", 
sex = raw_input() 

print "Let me see if I understood correctly. Your complete name is %r %r, you live in %r, rides on a %r, and you are a %r $r." % (name, middle_name, country, car, socstatus, sex) 

Answer 1

這是一個簡單的語法問題：你的最後的格式規範似乎是$ R代替％R。正因爲如此，你只有五種格式規格，但六個變量。改變最後一個。

print "Let me see if I understood correctly. Your complete name is %r %r, 
you live in %r, rides on a %r, and you are a %r %r." % (name, middle_name, 
country, car, socstatus, sex) 

Answer 2

您使用$ r而不是％r作爲最終變量。

Answer 3

您在格式字符串中有$r，而不是%r。但是，請記住，％r格式樣式已被棄用。你應該使用str.format（），它當前支持位置參數。

# Get variables... 
print("Let me see if I understood correctly. Your complete name is {} {}, you live in {}, rides on a {}, and you are a {} {}.".format(name, middle_name, country, car, socstatus, sex))
