1 字符串比较函数
1.1 numpy.char.equal()
char.equal(x1, x2)
判断
x1 == x2
是否是真的。
Example:
print(np.char.equal(\'Blair\',\'blair\'))print(np.char.equal(\'Blair\',\'Blair\'))\"\"\"FalseTrue\"\"\"
1.2 numpy.char.not_equal()
char.not_equal(x1, x2)
判断
x1 == x2
是否不是真的。
Example:
print(np.char.not_equal(\'Blair\',\'blair\'))print(np.char.not_equal(\'Blair\',\'Blair\'))\"\"\"TrueFalse\"\"\"
1.3 numpy.char.greater_equal()
char.greater_equal(x1, x2)
判断
(x1 >= x2)
。
Example:
print(np.char.greater_equal(\'Blair\',\'blair\'))print(np.char.greater_equal(\'Blair\',\'Blair\'))print(np.char.greater_equal(\'abc\',\'abd\'))print(np.char.greater_equal(\'abc\',\'Abd\'))\"\"\"FalseTrueFalseTrue\"\"\"
1.4 numpy.char.less_equal()
char.less_equal(x1, x2)
判断
(x1 <= x2)
。
Example:
print(np.char.less_equal(\'Blair\',\'blair\'))print(np.char.less_equal(\'Blair\',\'Blair\'))print(np.char.less_equal(\'abc\',\'abd\'))print(np.char.less_equal(\'abc\',\'Abd\'))\"\"\"TrueTrueTrueFalse\"\"\"
1.5 numpy.char.less()
char.less(x1, x2)
判断
(x1 < x2)
。
Example:
print(np.char.less(\'Blair\',\'blair\'))print(np.char.less(\'Blair\',\'Blair\'))print(np.char.less(\'abc\',\'abd\'))print(np.char.less(\'abc\',\'Abd\'))\"\"\"TrueFalseTrueFalse\"\"\"
