swap function in python code example

Example 1: swapping in python

x = 5
y = 10

x, y = y, x
print("x =", x)
print("y =", y)

Example 2: code to swap in python

a=5
b=10
a,b=b,a  #swapped

Example 3: swap variables in python

a = 5
b = 6
# now swp the variables
a, b = b, a
# to swap two variables you need an other string harder than the first one
c = a	# 5
a = b	# 6
b = c	# 5

Example 4: swapping variables in python

a = 1
b = 2

a, b = b, a
# a = 2 , b = 1

Example 5: python swap two variables

a = 2
b = 4
print (a) # 2
print (b) # 4
# Now swap them
# Hold one variable in c temporarily:
c = b
b = a
a = c
# Now delete variable c from memory:
del c

print (a) # 4
print (b) # 2

Example 6: python swap function

def swap0(s1, s2):
    assert type(s1) == list and type(s2) == list
    tmp = s1[:]
    s1[:] = s2
    s2[:] = tmp
    
# However, the easier and better way to do a swap in Python is simply:
s1, s2 = s2, s1
