Can some one tell me how should I go to the next line? for solving this i used ";" but it doesn't work here.

Answer 1

thats correct, python uses new lines and indents, not semicolons it should go:
age=input()
name=input()
if int(age) <5:
print(name + ' is a child.')
# see above how print is indented?

Answer 2

post your code so we can help please

I think that is because of the "if" that is not entered on the next line with its condition
age = input() ; name = input() ;
if int(age) < 5: print(name+'child')

Do you mean typing the input?
Then try it like this:
4
Myname
# 4 will be assigned to "age" variable and Myname will be assigned to "name" variable. It is because semicolon means next line of the program.

Or if what you are trying to do is to get the input on the same line.
For example like this:
4 Myname
# Then you can use "Unpacking of values".
- - - - - - - - - - - - - - - - - - - -
age, name = input().split()
string.split() converts the string to list by whitespace by default (you can split the string whatever character you want). For example:
"4 Myname".split()
>> [ "4", "Myname" ]
Then we unpack this list
age, name = [ "4", "Myname" ]
age ---> "4"
name ---> "Myname"

Answer 6

No , I meant when I want to write the codes, not inputs.

Answer 7

age=input() ; name=input() ; if age<5:print(name+' is a child.')
If i write like this an error happens.
But
age=input()
name=input()
if age<5:print(name + ' is a child.')
Is correct.

Answer 8

I don't know how to go next line and when i press enter the program will run.
