[英]Python / xldr : How do I pull data from an excel file using a raw_input variable?
[英]How do I insert a variable into a raw_input query?
我已經從“以艱難的方式學習Python”這本書開始學習Python2.7.x。 我目前正在學習raw_input
函數,並且正在嘗試使用不同的方法來使用它。 我寫了以下代碼:
name = raw_input("What is your name? ")
print "Hi %s," % name,
home = raw_input("where do you live? ")
print "I hear that %s is a great place to raise a family, %s." % (home, name)
age = raw_input("How old are you, %s? ") % name
我在最后一行收到此錯誤:
TypeError: not all arguments converted during string formatting
我如何以類似的方式使用raw_input
函數並插入變量,以便自定義raw_input
查詢中嵌入的問題(如果弄亂了術語,我raw_input
表歉意)?
理想情況下,我想按照以下思路輸出問題:
How old are you, Bob?
嘗試:
age = raw_input("How old are you, %s? " % name)
說明:
raw_input([prompt])
If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that.
所以,當你這樣做
age = raw_input("How old are you, %s? ") % name
假設您進入了Paul
所以上面的陳述變成
age = "Paul" % name
並且由於字符串“ Paul”不是占位符,因此會引發相應的錯誤。
