Python | Rear stray character String split

Sometimes, while working with Python Strings, we can have problem in which we need to split a string. But sometimes, we can have a case in which we have after splitting a blank space at rear end of list. This is usually not desired. Lets discussed ways in which this can be avoided.

Method #1 : Using split() + rstrip()
The combination of above functions can be used to solve this problem. In this, we remove the stray character from the string before split(), to avoid the empty string in split list.

# Python3 code to demonstrate working of
# Rear stray character String split
# Using split() + rstrip()

# initializing string
test_str = 'gfg, is, best, '

# printing original string
print("The original string is : " + test_str)

# Rear stray character String split
# Using split() + rstrip()
res = test_str.rstrip(', ').split(', ')

# printing result
print("The evaluated result is : " + str(res))

Output :

The original string is : gfg, is, best,
The evaluated result is : ['gfg', 'is', 'best']

Method #2 : Using split()
The use of rstrip() can be avoided by passing additional arguments while performing the split().

# Python3 code to demonstrate working of
# Rear stray character String split
# Using split()

# initializing string
test_str = 'gfg, is, best, '

# printing original string
print("The original string is : " + test_str)

# Rear stray character String split
# Using split()
res = test_str.split(', ')[0:-1]

# printing result
print("The evaluated result is : " + str(res))

Output :

The original string is : gfg, is, best,
The evaluated result is : ['gfg', 'is', 'best']
