我希望可以通过循环让x变成x1=[],x2=[],x3=[]
比如说第一次循环是x1，第二次变成x2
```python
import re
import os
import numpy as np
files = []
x=[]
y=[]
i=0
j=0
dir_file_path = 'xukka'
for file in os.listdir(dir_file_path):
if re.findall('.*?txt',file):
files.append(file)
for name in files:
a = np.loadtxt(name)
x.append(a[:,0])
y.append(a[:,1])
print(x)
for i in len(x): #这里让x变成x1，x2,x3
print(x)
```
这样？
import re
import os
import numpy as np
files = []
x=[]
y=[]
i=0
j=0
dir_file_path = 'xukka'
for file in os.listdir(dir_file_path):
if re.findall('.*?txt',file):
files.append(file)
for name in files:
a = np.loadtxt(dir_file_path+'/'+name)
x.append(a[:,0])
y.append(a[:,1])
for i in range(len(x)): #这里让x变成x1，x2,x3
if i==0:
x1=x[i]
elif i==1:
x2=x[i]
else:
x3=x[i]
print(x1)
print(x2)
print(x3)
