IOError: [Errno 2] 没有这样的文件或目录:
import os
try:
os.path.exists("E:/Contact") #Check if dir exist
except:
os.mkdir("E:/Contact") #if not, create
def add(name,cell,email): #add contact
conPath0 = 'E:/Contact'
conPath1 = '/ '
conPath1b = conPath1.strip()
conPath2 = name+'.txt'
conPath = conPath0+conPath1b+conPath2
file = open(conPath,'w')
file.write('Name:'+ name+'\n') #write into file
file.write('Cell:'+ cell+'\n')
file.write('Email:'+ email+'\n')
file.close()
def get(name): #get contact
conPath0 = 'E:/Contact'
conPath1 = '/ '
conPath1b = conPath1.strip()
conPath2 = name+'.txt'
conPath = conPath0 + conPath1b + conPath2
try:
os.path.exists(conPath) #check if exist
file = open(conPath,'r')
getFile = file.readlines()
print(getFile)
except:
print("Not Found!")
def delete(name): #delete contact
conPath0 = 'E:/Contact'
conPath1 = '/ '
conPath1b = conPath1.strip()
conPath2 = name+'.txt'
conPath = conPath0 + conPath1b + conPath2
try:
os.path.exists(conPath)
os.remove(conPath)
print(name+"has been deleted!")
except:
print("Not Found!")
当我输入这个:
add('jack','222','ds@gmail.com')
我得到了这个:
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
add('jack','222','ds@gmail.com')
File "E:/lab/t.py", line 13, in add
file = open(conPath,'w')
IOError: [Errno 2] No such file or directory: 'E:/Contact/jack.txt'
我试过 E:\Contact,但还是不行。 我第一次运行成功了,但之后就不行了。 我还是个新手,如果我的代码不好请多多包涵。谢谢。

如果路径不存在,os.path.exists 这个函数会返回 False,而不是抛出一个错误。所以代码的第一部分没有按预期工作。可以用下面这个来替代。
if not os.path.exists("E:/Contact"):
os.mkdir("E:/Contact")
