我编写了这个示例程序,旨在从计算机打开一个文本文件(database1.txt),并显示文件中当前的结果。如果他们的名字在文档中,则提示使用,如果是则应打印文本文件的内容然后关闭,否则应提示用户输入他们的名字,然后程序将名称写入相同的文本文档,然后再次打印文本文件的内容,以便用户可以看到新添加的数据。我输入了代码,不知何故它一直说我有语法错误。我检查了几次,我无法修复错误。我想知道是否有人可以看一下,他们是否可以向我解释错误。谢谢
#This program reads/writes information from/to the database1.txt file
def database_1_reader ():
print('Opening database1.txt')
f = open('database1.txt', 'r+')
data = f.read()
print data
print('Is your name in this document? ')
userInput = input('For Yes type yes or y. For No type no or n ').lower()
if userInput == "no" or userInput == "n"
newData = input('Please type only your First Name. ')
f.write(newData)
f = open ('database1.txt', 'r+')
newReadData = f.read()
print newReadData
f.close()
elif userInput == "yes" or userInput == "ye" or userInput == "y"
print data
f.close()
else:
print("You b00n!, You did not make a valid selection, try again ")
f.close()
input("Presss any key to exit the program")
database_1_reader()
