Python|如果大于 n，则从元组列表中删除元组

给定一个元组列表，任务是从列表中删除所有元组，如果它大于n （比如 100）。让我们讨论一些相同的方法。

方法 #1：使用 lambda

# Python code to demonstrate
# to remove the tuples
# if certain criteria met
  
# initialising _list
ini_tuple = [('b', 100), ('c', 200), ('c', 45),
                         ('d', 876), ('e', 75)]
  
# printing iniial_tuplelist
print("intial_list", str(ini_tuple))
  
# removing tuples for condition met
result = [i for i in ini_tuple if i[1] <= 100]
  
# printing resultant tuple list
print ("Resultant tuple list: ", str(result))
             

输出：

intial_list [(‘b’, 100), (‘c’, 200), (‘c’, 45), (‘d’, 876), (‘e’, 75)]
Resultant tuple list: [(‘b’, 100), (‘c’, 45), (‘e’, 75)]

方法 #2：使用过滤器 + lambda

# Python code to demonstrate
# to remove the tuples
# if certain criteria met
  
# initialising _list
ini_tuple = [('b', 100), ('c', 200), ('c', 45),
                         ('d', 876), ('e', 75)]
  
# printing iniial_tuplelist
print("intial_list", str(ini_tuple))
  
# removing tuples for condition met
result = list(filter(lambda x: x[1] <= 100, ini_tuple))
  
# printing resultant tuple list
print ("Resultant tuple list: ", str(result))

输出：

intial_list [(‘b’, 100), (‘c’, 200), (‘c’, 45), (‘d’, 876), (‘e’, 75)]
Resultant tuple list: [(‘b’, 100), (‘c’, 45), (‘e’, 75)]

方法#3：使用朴素方法

# Python code to demonstrate
# to remove the tuples
# if certain criteria met
  
# initialising _list
ini_tuple = [('b', 100), ('c', 200), ('c', 45), 
                         ('d', 876), ('e', 75)]
  
# printing iniial_tuplelist
print("intial_list", str(ini_tuple))
  
# removing tuples for condition met
result = []
for i in ini_tuple:
    if i[1] <= 100:
        result.append(i)
  
# printing resultant tuple list
print ("Resultant tuple list: ", str(result))
            

输出：

intial_list [(‘b’, 100), (‘c’, 200), (‘c’, 45), (‘d’, 876), (‘e’, 75)]
Resultant tuple list: [(‘b’, 100), (‘c’, 45), (‘e’, 75)]
