                       And

Requires all given `ParseExpression`s to be found in the given order. Expressions may be separated by whitespace. May be constructed using the `'+'` operator. May also be constructed using the `'-'` operator, which will suppress backtracking.

Example:

       integer = Word(nums)
       name_expr = OneOrMore(Word(alphas))

       expr = And([integer("id"),name_expr("name"),integer("age")])
       # more easily written as:
       expr = integer("id") + name_expr("name") + integer("age")
