Python operator.gt()用法及代碼示例

operator.gt() 函數

operator.gt()函數是一個庫函數operator模塊，用於對兩個值執行“大於操作”並返回True如果第一個值大於第二個值，False，否則。

模塊：

    import operator

用法:

    operator.gt(x,y)

參數：

• x,y– 要比較的值。

返回值：

這個方法的返回類型是bool，它返回True如果x大於y，False，否則。

範例1：

# Python operator.gt() Function Example

import operator

# integers
x = 10
y = 20

print("x:",x, ", y:",y)
print("operator.gt(x,y):", operator.gt(x,y))
print("operator.gt(y,x):", operator.gt(y,x))
print("operator.gt(x,x):", operator.gt(x,x))
print("operator.gt(y,y):", operator.gt(y,y))
print()

# strings
x = "Apple"
y = "Banana"

print("x:",x, ", y:",y)
print("operator.gt(x,y):", operator.gt(x,y))
print("operator.gt(y,x):", operator.gt(y,x))
print("operator.gt(x,x):", operator.gt(x,x))
print("operator.gt(y,y):", operator.gt(y,y))
print()

# printing the return type of the function
print("type((operator.gt(x,y)):", type(operator.gt(x,y)))

輸出：

x:10 , y:20
operator.gt(x,y): False
operator.gt(y,x): True
operator.gt(x,x): False
operator.gt(y,y): False

x:Apple , y:Banana
operator.gt(x,y): False
operator.gt(y,x): True
operator.gt(x,x): False
operator.gt(y,y): False

type((operator.gt(x,y)): <class 'bool'>

範例2：

# Python operator.gt() Function Example
import operator

# input two numbers
x = int(input("Enter first number:"))
y = int(input("Enter second number:"))

# printing the values
print("x:",x, ", y:",y)

# comparing
if operator.gt(x,y):
  print(x, "is greater than", y)
else:
  print(x, "is not greater than", y)

輸出：

RUN 1:
Enter first number:20
Enter second number:10
x:20 , y:10
20 is greater than 10

RUN 2:
Enter first number:10
Enter second number:20
x:10 , y:20
10 is not greater than 20
