Write a Python program to convert the given list into a single integer. Given List of integer Input: list1 = [1,2,3,4,5] output: 12345 With the help of join method we can do this easily Method 1: Without Method 
# Converting integer list to string list 
s_ints = [str(i) for i in list1 ]

# Join list items using join()
str_result = "".join(s_ints)

#convert string to integer
res = int(str_result) Method 2: Using method 
def join_list_data(list):
 result= ''
 for item in list:
 result += str(item)
 
 return result

result = join_list_data(list1)

#convert string to integer
result = int(result)
print(result)
