How to remove square brackets from data in python

Usually when Python outputs a list string, it will automatically add quotation marks and brackets.

For example (recommended learning: Python video tutorial)

str=['hello','world']
>>> str
['hello', 'world']

Method 1

You can use the join method:

>>> print " ".join(str)
hello world

Among them: The Python join() method is used to connect the elements in the sequence with the specified characters to generate a new string.

For example:

str = "-"
seq = ("a", "b", "c")
print str.join( seq )

Output result:

a-b-c

Method 2: If the list stores numbers, then: just convert it to int. Because the original storage is string type

str=['1', '2', '3']
for i in str:    
    int(i)  
    print(i)
