在Python中,我们可以使用bin()或format()将整数转换为二进制字符串表示形式。
print
(
bin
(
1
))
# 0b1
print
(
bin
(
-
1
))
# -0b1
print
(
bin
(
10
))
# 0b1010
print
(
bin
(
-
10
))
# -0b1010
print
(
"{0:b}"
.
format
(
10
))
# 1010
print
(
"{0:#b}"
.
format
(
10
)) #
0b1010
, with
0b
prefix
print
(
"{0:b}"
.
format
(
10
).zfill(
8
))
# 00001010 , pad zero, show 8 bits
print
(
format
(
10
,
"b"
))
# 1010
print
(
format
(
10
,
"#b"
)) #
0b1010
, with
0b
prefix
print
(
format
(
10
,
"b"
).zfill(
16
))
# 0000000000001010, pad zero, show 16 bits
# with hex, oct bin
# int: 10; hex: a; oct: 12; bin: 1010
result
=
"int: {0:d}; hex: {0:x}; oct: {0:o}; bin: {0:b}"
.
format
(
10
)
print
(result)
# with 0x, 0o, or 0b as prefix:
# int: 10; hex: 0xa; oct: 0o12; bin: 0b1010
result
=
"int: {0:d}; hex: {0:#x}; oct: {0:#o}; bin: {0:#b}"
.
format
(
10
)
print
(result)
