Contact Search

Question

Hey, guys. Please help with the task. I do not understand at all how to extract a separate element in this task. I got something like this:
contacts = [
('James', 42),
('Amy', 24),
('John', 31),
('Amanda', 63),
('Bob', 18)
]

name = input()

if name == contacts[0]
print("James is 42")

But it does't work. I don't understand

Answer 1

contacts = [
('James', 42),
('Amy', 24),
('John', 31),
('Amanda', 63),
('Bob', 18)
]

x = input()

for i in contacts:
if x in i:
print(f"{x} is {i[1]}")
break
else:
print('Not found')

## else outside of the for loop, or it will put i "Not found"

Answer 2

contacts = [
('James', 42),
('Amy', 24),
('John', 31),
('Amanda', 63),
('Bob', 18)
]

name=input()
count=1
for i in contacts:
if i[0]==name :
age= i[1]
print(str(name) + " is " + str(age) )
break
elif count>=len(contacts) :
print("Not Found")
count +=1

Answer 3

This is task

You are given a list of contacts, where each contact is represented by a tuple, with the name and age of the contact.
Complete the program to get a string as input, search for the name in the list of contacts and output the age of the contact in the format presented below:

Sample Input:
John

Sample Output:
John is 31

Answer 4

I mean that i can't understand how can I split the values in tuples

Answer 5

Tuple can be accessed using the same method to access lists.

Here is an example for accessing the values in the lists and tuples in this question:
contacts[0] = ('James', 42)
contacts[0][0] = James
contacts[0][1] = 42

After you understand how to access the values, you can apply for loop to accomplish your task. Let me know if you have further questions.

Answer 6

Name=input ()
Contact_search:{
'Umesh':21,
'Gokul':20,
'Lokesh':23,

'Shanker':26,
'Dhoni':33
}
print (Contact_search.get(Name,"Not found")

('James', 42),
('Amy', 24),
('John', 31),
('Amanda', 63),
('Bob', 18)
]
name = input()
if name in contacts[0]:
x = contacts[0]
y = x[0]
b = x[-1]
print(y + ' is' ,b)
elif name in contacts[1]:
x = contacts[1]
y = x[0]
b = x[-1]
print(y + ' is' ,b)
elif name in contacts[2]:
x = contacts[2]
y = x[0]
b = x[-1]
print(y + ' is' ,b)
elif name in contacts[3]:
x = contacts[3]
y = x[0]
b = x[-1]
print(y + ' is' ,b)
elif name in contacts[4]:
x = contacts[4]
y = x[0]
b = x[-1]
print(y + ' is' ,b)
else:
print('Not found')

Answer 10

The "solution" that Sololearn provides for this does not even solve all of the Test Cases. Seyed Jalal Mazloomi's solution in this thread provided solutions for all Test Cases.

Answer 11

That is very true the solution by Sololearn is not working for me.
