Python elements are re-scrambled together

Suppose Aaa= "James", write out all combinations of letters, such as AMESJ,MESJA ...

Import itertoolsaaa=list (Itertools.permutations ("James", 5)) #核心语句, followed by 5, that is, 5 letters are arranged for I in Aaa:print ("". Join (i)) # I is a string that uses a join to fit a single string element

"Comment" permutations is the whole arrangement, but there is also a usage called combinations, this usage is not repeated arrangement, such as Itertools.combinations ("abc", 2) words, ("A, B") and ("B.", "a") As the result is the same, and permutation the result as two results.
