Python|打印不带引号的列表的方法

每当我们在Python中打印 list 时，我们通常使用 str(list)，因为我们在输出列表中有单引号。假设问题是否需要打印不带引号的解决方案。让我们看看一些打印不带引号的列表的方法。

方法 #1：使用map()

# Python code to demonstrate 
# printing list in a proper way
  
# Initialising list
ini_list = ['a', 'b', 'c', 'd']
  
# Printing initial list with str
print ("List with str", str(ini_list))
  
# Printing list using map
print ("List in proper method", '[%s]' % ', '.join(map(str, ini_list)))

输出：

List with str ['a', 'b', 'c', 'd']
List in proper method [a, b, c, d]

方法 #2：使用sep方法

# Python code to demonstrate 
# printing list in proper way
  
# Initialising list
ini_list = ['a', 'b', 'c', 'd']
  
# Printing initial list with str
print ("List with str", str(ini_list))
  
# Printing list using sep Method
print (*ini_list, sep =', ')

输出：

List with str ['a', 'b', 'c', 'd']
a, b, c, d

方法 #3：使用 .format()

# Python code to demonstrate 
# printing list in proper way
  
# Initialising list
ini_list = ['a', 'b', 'c', 'd']
  
# Printing initial list with str
print ("List with str", str(ini_list))
  
# Printing list using .format()
print ("Printing list without quotes", ("[{0}]".format(
                       ', '.join(map(str, ini_list)))))

输出：

List with str ['a', 'b', 'c', 'd']
Printing list without quotes [a, b, c, d]

方法#4：使用translate方法

# Python code to demonstrate 
# printing list in proper way
  
# Initialising list
ini_list = ['a', 'b', 'c', 'd']
  
# Printing initial list with str
print ("List with str", str(ini_list))
  
translation = {39: None}
# Printing list using translate Method
print ("Printing list without quotes", 
        str(ini_list).translate(translation))

输出：

List with str ['a', 'b', 'c', 'd']
Printing list without quotes [a, b, c, d]
