【问题描述】：
这是我的代码：
from getch import getch
from replit import clear
test1 = []
code = {
"!" : "!","@" : "@","?" : "?","." : ".","," : ","," " : " ","#" : "#","$" : "$","%" : "%","^" : "^","&" : "&","`" : "`","~" : "~","_" : "_","=" : "=","\\" : "\\","|" : "|","[" : "[","{" : "{","]" : "]","}" : "}",";" : ";",":" : ":","'" : "'",'"' : '"',"<" : "<",">" : ">","/" : "/","a" : "7","b" : "8","c" : "9","d" : "4","e" : "5","f" : "6","g" : "1","h" : "2","i" : "3","j" : "÷","k" : "*","l" : "-","m" : "+","n" : "(7)","o" : "(8)","p" : "(9)","q" : "(4)","r" : "(5)","s" : "(6)","t" : "(1)","u" : "(2)","v" : "(3)","w" : "(÷)","x" : "(*)","y" : "(-)","z" : "(+)","A" : "7","B" : "8","C" : "9","D" : "4","E" : "5","F" : "6","G" : "1","H" : "2","I" : "3","J" : "÷","K" : "*","L" : "-","M" : "+","N" : "(7)","O" : "(8)","P" : "(9)","Q" : "(4)","R" : "(5)","S" : "(6)","T" : "(1)","U" : "(2)","V" : "(3)","W" : "(÷)","X" : "(*)","Y" : "(-)","Z" : "(+)"
}
while True:
test = getch()
if (test = "\x7f"):
test1=test1[:-1]
else:
test1.append(test)
clear()
print("".join(str(code[c]) for c in test1) )
在第 9 行，它告诉我我有一个语法错误，即使我输入正确，你们能帮我解决这个问题吗？如果解决了，它是否按预期工作
（这是在 repl.it 中编码的）
【问题讨论】：
-
如果测试 == ---.
-
需要'=='比较运算符而不是'='（赋值）
-
啊，是的，这就是它所需要的。我从编码中休息了 3 个月，好像忘记了一些小事情
-
您不需要在 Python 中的
if语句中的条件周围加上括号。
