Pythonの基本-演算子

演算子

1. 算術演算: +、-、*、/、%、**、//

print (3+2) => 5print (3-2) => 1print (2*4 ) => ; 8print (9/3) => 3print (2**2) => 49print (9//2) => 2. ,!=,<>,>,<,>=,<=

print (3==2) => Falseprint (3!=2) => 4) => True # は !=print (9>3) => Trueprint (100>=51) => Trueprint に統合されました;=2) => False

3. 代入演算: =,+=,-=,*=,/=,%=,**=,//=

a = 5print (a) => ; 5a = 5b = 1b += a # b=b+aprint (b) => 6a = 5b = 1b -= a # b=b-aprint (b) => -4a = 5b = 1b * = a # b= b*aprint (b) => 5a = 5b = 1b /= a # b = b/aprint (b) => 0.2a = 5b = 1b **= a # b = b** aprint ( b) => 1a = 5b = 1b %= a # b = b%aprint (b) => 1a = 5b = 1b //= a # b = b//aprint (b) => 0

4. 論理計算: and, or ,not

a = Trueb = Falseprint (a and b) => False # a と b が両方とも true の場合にのみ true print (a or b) => True # a または b のいずれかが true である限り、それは true print (not a) => False # Not true print (not b) => True # Not false

5.

a = [11,22,33,44]

b = 11
c = 123

print (a に b) =>True

print (c は a にない) =>True
