Make a comment
 
#this is a comment

Convert other data type to string

Operation with List (array)

Descri­ption
Syntax (Code)
Print Console
Creating a list
 
daily_temp = [80,90,54]
Remember, Index starts with 0
Print out a particular index
 
print(­dai­ly_­tem­p[2])
54
Reassi­gning a new value to particular index
 
daily_­temp[2] = 100
[80,90­,100]
Printing each index using a 
for
loop
 
for i in range 3:

 
print(­dai­ly_temp [i])
80
90
100
To get the length of the list
and assign to a variable
 
x = len(da­ily­_temp)
x : 3
To print a list without a definitive length
 
for i in range(len(daily_high_temps)): 
 print(daily_high_temps[i])
80
90
100
Second easier way to loop and print through a list
 
for i in daily_­temps: 
   print(i):
80
90
100
