sprintf(format, [relax=1]) -> str
Where format is a string that can include directives. A directive
begins and ends by % and has the following format:
``%[fmt[r],][cls[:nb].]field%``
:param fmt: is a classic printf directive, "r" can be appended for raw
substitution:
(ex: IP.flags=0x18 instead of SA), nb is the number of the layer
(ex: for IP/IP packets, IP:2.src is the src of the upper IP layer).
Special case : "%.time%" is the creation time.
Ex::
p.sprintf(
"%.time% %-15s,IP.src% -> %-15s,IP.dst% %IP.chksum% "
"%03xr,IP.proto% %r,TCP.flags%"
)
Moreover, the format string can include conditional statements. A
conditional statement looks like : {layer:string} where layer is a
layer name, and string is the string to insert in place of the
condition if it is true, i.e. if layer is present. If layer is
preceded by a "!", the result is inverted. Conditions can be
imbricated. A valid statement can be::
p.sprintf("This is a{TCP: TCP}{UDP: UDP}{ICMP:n ICMP} packet")
p.sprintf("{IP:%IP.dst% {ICMP:%ICMP.type%}{TCP:%TCP.dport%}}")
A side effect is that, to obtain "{" and "}" characters, you must use
"%(" and "%)".

It helps to see which packets exists in contrib or layer files.
params:
- layer: If specified, the function will explore the layer. If not,
the GUI mode will be activated, to browse the available layers
examples:
>>> explore() # Launches the GUI
>>> explore("dns") # Explore scapy.layers.dns
>>> explore("http2") # Explore scapy.contrib.http2
>>> explore(scapy.layers.bluetooth4LE)
Note: to search a packet by name, use ls("name") rather than explore.
