print '{' using .format

I want to print the string: [{X}], while X is an int. when I'm using .format I get into trouble with printing the char '{' because it's a part of the format.

I tried to use the code line: 

print("[{{}}]".format(X))

and I get the error: 

Single '}' encountered in format string.

Is there a way around this error?

If using format() isn't an absolute necessity, then you can do something like that:

x = 12
print("[{%i}]" %x)
# [{12}]

Which is way cleaner and more understandable than:

print("[{{{}}}]".format(X))

While I can't reproduce the error you claim, you only produce the characters needed to display the braces, with no replacement field.

fmt = "["  # the opening bracket
fmt += "{{"  # the literal {
fmt += "{}"  # the replacement field
fmt += "}}"  # the literal }
fmt += "]"  # the closing bracket

assert fmt == "[{{{}}}]"
#         not "[{{}}]", as you have

assert fmt.format(3) == "[{3}]"

{{}} are used to print {}. If you want something like this {something}. Try this

X=10
print("[{{{}}}]".format(X))
# [{10}]
