[英]file.read returning empty list
file1.seek(0)
exec(i + ".seek(0)")
readd = exec(i + ".readlines()")
print(file1.readlines())
I have already opened the file as "r+" the file contains content, but the code returns this: 我已经以“ r +”打开文件,文件包含内容,但是代码返回以下内容:
[]
None
I did seek to the beginning but it still doesn't return the contents any help is appreciated! 我确实是从头开始的,但仍然没有返回任何内容,感谢任何帮助!
this is the full code: 这是完整的代码:
dictt = {'a':'z','b':'x','c':'c','d':'v','e':'b',
'f':'n','g':'m','h':'a',
'i':'s','j':'d','k':'f','l':'g','m':'h',
'n':'j','o':'k','p':'l','q':'ñ',
'r':'q','s':'w','t':'e','u':'r','v':'t',
'w':'y','x':'u','y':'i','z':'o', "ñ" : "p",
" " : "m", "\\" : "m"
}
inv_map = {v: k for k, v in dictt.items()}
def read():
file1 = open("memory1.txt", "r+")
i = input("file: ")
o = input("Note: ")
exec(i + ".seek(0)")
readd = exec(i + ".readlines()")
readd = file1.readlines()
readd = str(readd)
lent = len(readd)
final = ""
for i in range(lent - 4):
final += inv_map[str(readd[i + 2])]
print(final)
print("Note: " + o)
file1.close()
def write():
file1 = open("memory1.txt", "r+")
n = input("to file: ")
m = str(input("Go: "))
print(n)
lent = len(m)
for i in range(lent):
exec(n + ".write(dictt[m[i]])")
print(dictt[m[i]])
print("Wrote: ", m)
file1.close()
while (cont == True):
y = input()
print(".")
final = y + "(" + ")"
exec(final)
the write function works fine btw 写功能正常工作顺便说一句
you already read the file using 您已经使用读取了文件
readd = exec(i + ".readlines()")
this will returns the content of file to the readd variable. 这会将文件的内容返回到readd变量。 The next line,
下一行
print(file1.readlines())
will again call readlines which will return an empty list. 将再次调用readlines,这将返回一个空列表。
