[Python] Complex list comprehension - one liner

I attempted to create a one-liner to print out this ("the non-perfect list of safe characters for filenames, in most operating systems"):

$ python ./z.py
+,-.
0123456789
@ABCDEFGHIJKLMNOPQRSTUVWXYZ[]^_
abcdefghijklmnopqrstuvwxyz{}~


...but have not found a way to do it; so had to create a short script instead

My final one-liner attempt:

$ python -c "lst= [ [0x2b,0x2e+1],[0x30,0x39+1],[0x40,0x5f+1],[0x61,0x7f+1] ];print( [ chr(c) if (c & 0xdf)!=0x5c else '' for c in [ range(a,b) for a,b in [ li for li in lst ] ] ] )"
Traceback (most recent call last):
File "<string>", line 1, in <module>
TypeError: unsupported operand type(s) for &: 'range' and 'int'


the above output created by z.py containing:

#!/bin/env python

# copy of the one-liner
# python -c "lst= [ [0x2b,0x2e+1],[0x30,0x39+1],[0x40,0x5f+1],[0x61,0x7f+1] ];print( [ chr(c) if (c & 0xdf)!=0x5c else '' for c in [ range(a,b) for a,b in [ li for li in lst ] ] ] )"

# attempt to break down of the above
# python -c "lst= [ [0x2b,0x2e+1],[0x30,0x39+1],[0x40,0x5f+1],[0x61,0x7f+1] ];print(
# [ chr(c) if (c & 0xdf)!=0x5c else '' for c in
# [ range(a,b) for a,b in
# [ li for li in lst ]
# ]
# ]
# )"

# working code to create the output
lst= [ [0x2b,0x2e+1],[0x30,0x39+1],[0x40,0x5f+1],[0x61,0x7f+1] ]

for li in lst:
a,b=li
for c in range(a,b):
z=(c & 0xdf)
if z != 0x5c:
print(chr(c), end='')
print()


Where is the problem with the one liner, can you pinpoint how to do it?
