我正在尝试制作一个接受用户输入并对其进行修改的程序(用户输入将是各种10位数的数字字符串),然后返回修改后的结果。目前,我可以通过单行输入实现我想要的功能,但是我想添加功能,以允许用户输入多个输入,并让程序分别修改每个输入。但是,在当前状态下,尽管位于单独的行中,它仍将简单地修改文本框中的所有内容,就好像它是一个长字符串一样。
我当时想我可以尝试将文本框中的每个输入都变成一个列表,然后以这种方式进行迭代?我不确定是否有更好的方法可以做到这一点?
import tkinter as tk
root = tk.Tk()
def returnEntry(arg=None):
rawresult = myEntry.get("1.0","end-1c")
#functionality here
modifiedresult = rawresult+str(' modded')
resultLabel.config(text=modifiedresult)
myEntry.delete(0,END)
canv = tk.Canvas(root,height=500,width=1000,bg='misty rose')
canv.pack()
myEntry = tk.Text(root, width=60)
myEntry.focus()
myEntry.bind("<Return>",returnEntry)
myEntry.place(relx=.05,rely=.1)
enterEntry = tk.Button(root, text= "Convert", command=returnEntry, bg='snow')
enterEntry.pack()
resultLabel = tk.Label(root, text = "")
resultLabel.place(relx=.55,rely=.1)
root.geometry("+700+400")
root.mainloop()
当前它仅修改文本框中的所有内容,就好像它是一个长字符串一样。
更新的代码:
def returnEntry(arg=None):
rawresult = myEntry.get("1.0","end-1c")
list_of_entries = []
for line in rawresult.splitlines():
list_of_entries.append(line.upper())
#--------------------------------------------------------------
#functionality here
for entries in list_of_entries:
modifiedresult = entries+str(' modded')
#--------------------------------------------------------------
resultLabel.config(text=modifiedresult)
myEntry.delete(0,END)
答案 0 :(得分:0)
只需使用str.splitlines()即可处理:https://www.tutorialspoint.com/python/string_splitlines.htm
my_text = """This is a very lenghty text example
To give an idea on operating
On strings using built-in method
string.splitlines()"""
repr(my_text)
"'This is a very lenghty text example\\nTo give an idea on operating\\nOn strings using built-in method\\nstring.splitlines()'"
注意您的代表字符串中的\ n。分隔线将文字“分解”为\ n(换行符)之间的片段。
## just print
for line in my_text.splitlines():
print(line+'\n')
## do some transormation
for line in my_text.splitlines():
print(line.lower()+'\n')
## append to a list to do some further transformation
some_list = []
for line in my_text.splitlines():
some_list.append(line.upper())
print(some_list[-1]+'\n')
