Python program to create a dictionary from a string

# Python3 code to convert
# string to dictionary

 
# Initializing String

string = "{` A`: 13, `B`: 14,` C`: 15} "

 
# eval () convert string to dictionary

Dict = eval (string)

print ( Dict )

print ( Dict [ `A` ])

print ( Dict [ `C` ])

Output: 

 {`C`: 15,` B`: 14, `A`: 13} 13 15

Method # 2: Using generator expressions in Python
If we receive string input that does not completely resemble a dictionary object, then we can use generator expressions to convert it to a dictionary.

# Python3 code to convert
# line to dictionary

 
# Init ializing String

string = "A - 13, B - 14, C - 15 "

  
# Convert string to dictionary

Dict = dict ((x.strip (), y.strip ()) for x, y in (element.split ( `-` ) for element in string.split ( `,` )))

 

print ( Dict ) 

print ( Dict [ `A` ])

print ( Dict [ `C` ])

Exit :

 {`C`:` 15`, `A`:` 13`, `B`:` 14`} 13 15

The above code does not convert integers to int type,

if there are integer keys, then only line 8 will work

string = "11 - 13, 12 - 14, 13 - 15"

 

Dict < code class = "keyword"> = dict ((x.strip (), int (y.strip ())) for x , y in (element.split ( `-` ) for element in string.split ( `,` )))

 

print ( Dict )

Exit:

 {`13`: 15,` 12`: 14, `11`: 13}
