python - My file has no length? Even though it does -

- 

def file_contents():     global file_encrypt     encryption_file = input("what name of file?")     file_encrypt = open(encryption_file, 'r')     contents = file_encrypt.read()     print (contents)     ask_sure = input("is file encrypt?")     if ask_sure == "no":         the_menu()

this part of code opens file user enters, right? there no real problems here.

def key_offset():     key_word = ''     count = 0     total = 0     while count < 8:         num = random.randint (33, 126)         letter = chr(num)         key_word = key_word + letter             count = count + 1         offset = ord(letter)         total = total + offset     print("make sure copy key decryption.")     if count == 8:         total = total/8         total = math.floor(total)         total = total - 32         print(key_word)         return total

this part calculates offset , etc etc. once again no problems here. 

def encrypting():     file = file_contents()     total = key_offset()     encrypted = ''     character_number = 0     length = len(file_encrypt)

and problem appears, have made variable file_encrypt global in first block of code, therefore should work. have tried calling under variable file_en = file_encrypt , used file_en in length calculating, keeps saying has no length... have tried asking friends , teacher, seem clueless. problem every time part says file_encrypt has no length or other way tried it, file_en has no length, textwrapper.io.

file_encrypt file pointer, indeed not have length. contents of file in contents, variable local file_contents function.

really should not using global variables; there isn't reason here. instead, return actual data - contents - file_contents, can use in calling function.
